Each One Teach One

James Whelton teaches two younger students as Bill Liao looks on in their Cork classroom

Cover Image Prompt (This is the Cover Image. Do not include this label in the image.) Please generate a wide-landscape 16:9 cover image in a warm, contemporary educational-graphic-novel style — clean linework, soft cel-shading, grounded realistic proportions. Scene: a Cork, Ireland classroom-turned-clubroom. James Whelton, a lean teenager of about eighteen with dark tousled hair and a black zip hoodie, leans over a laptop pointing something out to two younger boys seated at the table. Beside them stands Bill Liao, a man in his forties with East Asian features, glasses, dark hair, and a navy suit over a light blue shirt, holding a stack of papers headed with a checklist reading "mentor, plan, resources, outreach, sustain." Behind them a whiteboard reads "CORK, IRELAND / 2011" with a hand-drawn circle of stick figures and a flowchart reading "GROWING OUR CLUB: STUDENTS, SESSIONS, PROJECTS, COMMUNITY." Wall posters read "CODE CREATE CHANGE" and "Everyone Can Code." A large window behind them shows Cork's rooftops and a church spire under daylight. Title text "Each One Teach One" rendered in a bold, rounded, hand-lettered navy typeface across the top. Color palette: warm creams and browns with navy and teal accents. Emotional tone: mentorship, quiet pride, ambition at a small scale about to grow. Generate the image immediately without asking clarifying questions.
Narrative Prompt This is a real, historically documented story. James Whelton (born c. 1993) grew up in Cork, Ireland, and became locally known as a teenager for hacking the iPod Nano; he started an informal, then formal, computer club at his school, Presentation Brothers College (PBC), Cork, teaching classmates HTML and CSS. In 2011 he met entrepreneur and investor Bill Liao (born 1967, Australian, of Chinese and Irish—Australian heritage) at a Dublin tech/startup event; together they turned the club into CoderDojo, whose first official session was held 23 July 2011 at the National Software Centre in Cork. The movement grew to more than 1,250 Dojos across roughly 69 countries before CoderDojo merged with the Raspberry Pi Foundation in May 2017. Setting: Cork, Ireland, 2010–2011, with a closing panel set some years later at an international CoderDojo gathering. Art style: warm, contemporary educational-graphic-novel illustration, clean linework, soft cel-shading, a consistent color palette across panels. Bill Liao is drawn consistent with his real mixed Chinese-Australian appearance. Creative liberties, noted for transparency: (1) "Each One Teach One" is used here as this story's title because it captures CoderDojo's real peer-mentorship culture — young coders learning from slightly older coders, supported by adult mentors — but it is not the organization's literal recorded founding motto, which was "One Rule: Be Cool." (2) Panel 4's event banner, "Tech Ireland Startup Showcase 2011," stands in for the real venue where Whelton and Liao met and talked, the Dublin Web Summit. (3) Panel 3's whiteboard list of subjects (Python, data, apps, hardware, game dev, AI/ML) compresses how the curriculum broadened over CoderDojo's first years into a single classroom scene for narrative economy — the very first 2011 sessions centered on fundamentals like HTML, CSS, and Scratch. (4) Because text-to-image generation does not guarantee pixel-identical faces across many panels, James's exact appearance drifts slightly from panel to panel; Panel 8, set years after the founding, is meant to show both co-founders as established adults leading a movement that has become international.

Prologue – A Nerdy Kid Whose Thing Was Computers

James Whelton was not the star athlete or the top of his class at Presentation Brothers College in Cork. What he had was a laptop, a stubborn curiosity, and, at sixteen, enough skill to crack open Apple's iPod Nano and make it do things Apple never intended. That small act of local fame did something nobody expected: it made other kids at his school walk up and ask him to teach them how to do it too.

Panel 1: The iPod Hacker of Cork

James shows friends the iPod Nano hack that made him locally famous

Image Prompt (This is Panel 01. Do not include the panel number in the image.) I am about to ask you to generate a series of images for a graphic novel. Please make the images have a consistent style and consistent characters. Do not ask any clarifying questions. Just generate the image immediately when asked. Please generate a 16:9 image in a warm, contemporary educational-graphic-novel style depicting panel 1 of 8. The scene shows a bedroom-turned-workshop in Cork in 2010: James Whelton, a teenage boy with dark tousled hair in a black hoodie, sits at a desk holding an iPod Nano he has been modifying, cables running to an open laptop showing code. Four other teenage boys crowd around him, leaning in with excited, curious expressions. A small green-and-white flag hangs on the wall, a poster reads "CODE CREATE CHANGE," and bookshelves and a stack of books sit nearby. Through a window behind them, Cork's rooftops and a church spire are visible under daylight. Color palette: warm indoor lamplight against cool daylight from the window. Emotional tone: contagious, grassroots curiosity. Six visual details: the disassembled iPod Nano in James's hand, tangled cables on the desk, the laptop's code-filled screen, the green-and-white flag on the wall, the "CODE CREATE CHANGE" poster, the Cork skyline through the window. Generate the image immediately without asking clarifying questions.

Word had already gotten around school that James had cracked the iPod Nano — hacking together custom watch faces the device was never designed to show. Rather than keep it to himself, he started showing friends exactly how he'd done it, cables and code spread across his desk. He wasn't running a club yet. He was just doing what came naturally: when he figured something out, he taught it to whoever asked.

Panel 2: Forty Kids Show Up

James teaches HTML and CSS to a small group as a mentor observes

Image Prompt (This is Panel 02. Do not include the panel number in the image.) Please generate a 16:9 image in the same style depicting panel 2 of 8. Keep James consistent with the prior panel. The scene shows a school classroom at PBC Cork: James stands over a laptop showing a group of younger students — a girl and three boys — a simple "Hello, World" webpage, pointing at the code. A whiteboard behind them reads "Basics of Web Code" with HTML tags written out: html, head, title, body, h1 "Hello, World!," p tag. An adult mentor — a man in his forties with East Asian features, glasses, and a dark suit over a light blue shirt — stands just behind James, smiling, arms relaxed, clearly supporting rather than leading. Wall posters read "CODE CREATE CHANGE" and "Everyone Can Code." Other students work at laptops in the background. A window shows Cork's skyline. Color palette: warm classroom light, navy and teal accents. Emotional tone: eager first lessons, quiet mentorship. Six visual details: the whiteboard's HTML code, the "Hello, World!" heading, three open laptops, the mentor's checklist posture, the classroom's wall posters, the Cork skyline in the window. Generate the image immediately without asking clarifying questions.

James turned that curiosity into something more organized: a lunchtime computer club at his own school, teaching classmates the basics of HTML and CSS. "I didn't think there would be that much interest," he later said, "but more than 40 people showed up." Around this same stretch of 2011, James spoke about his iPod hack at a Dublin tech event and struck up a conversation with Bill Liao, an entrepreneur and investor who saw something worth nurturing in what James had already started — and began turning up to help.

Panel 3: The Club Outgrows the Room

A crowded classroom of students signs up to teach and learn at the growing club

Image Prompt (This is Panel 03. Do not include the panel number in the image.) Please generate a 16:9 image in the same style depicting panel 3 of 8. Keep James and the mentor consistent with prior panels. The scene shows a now-crowded classroom packed with teenagers at laptops in small clusters, far more students than panel 2. James stands centrally, gesturing while explaining something to a cluster of students. The mentor in the dark suit stands nearby, observing with arms folded, pleased. One whiteboard reads "GROWING OUR CLUB: STUDENTS, SESSIONS, PROJECTS, COMMUNITY" with a circular diagram of stick figures; a second whiteboard reads "WHAT WE CAN TEACH: PYTHON, WEB DESIGN, DATA, APPS, HARDWARE, GAME DEV, AI/ML, AND MORE!" with a sticky note reading "IDEAS PLANS IMPACT." In the foreground, a handwritten sign-up sheet on a clipboard reads "SIGN UP, GET INVOLVED, MAKE AN IMPACT" beside a small box of paper slips, with names, emails, and "what you can teach" / "interested in" columns filled in. Wall posters read "CODE CREATE CHANGE" and "Everyone Can Code." Color palette: warm, busy, full of activity. Emotional tone: momentum, a small club outgrowing its room. Six visual details: the sign-up clipboard, the two whiteboards, the sticky note, the crowd of laptops, the mentor's folded arms, the Cork skyline through the window. Generate the image immediately without asking clarifying questions.

The lunchtime club stopped fitting in one classroom. More students meant more laptops, more sign-up sheets, and older students teaching younger ones without anybody assigning them to do it — exactly the pattern James had started with his iPod hack, now repeating itself dozens of times over. Bill began sketching out, in the margins of his own notes, what it might look like if this stopped being one school's lunchtime club altogether.

Panel 4: A Conversation at a Startup Showcase

James and Bill Liao talk and sketch plans at a Cork tech event

Image Prompt (This is Panel 04. Do not include the panel number in the image.) Please generate a 16:9 image in the same style depicting panel 4 of 8. Keep James and Bill consistent with prior panels. The scene shows a tech conference venue with a banner reading "TECH IRELAND STARTUP SHOWCASE 2011," attendees with lanyards mingling in the background, a church spire visible through the windows. In the foreground, James sits across a table from Bill Liao, gesturing animatedly with both hands as he talks. Bill, in his dark suit, glasses, and light blue shirt, leans in, pen in hand, writing on a spiral notepad that reads "GROWING OUR CLUB" with a checklist: "students, sessions, projects, community" and a small diagram of stick figures connected by arrows. Open laptops sit on the table. Color palette: cool conference-hall tones warmed by the pair's focused conversation. Emotional tone: a serious, energized planning conversation between a teenager and an experienced mentor. Six visual details: the event banner, the spiral notepad with its checklist, James's animated hand gestures, Bill's pen mid-write, the lanyarded attendees in the background, the church spire through the window. Generate the image immediately without asking clarifying questions.

At the showcase, James and Bill kept talking past the small talk — about the shortage of programmers, about how many kids like the ones back at PBC never got a chance to try coding at all. Bill started writing as James talked, sketching the shape of an idea on his notepad: students, sessions, projects, community. What had been one school's lunchtime club was about to become a plan.

Panel 5: Sketching the Model

James and Bill draw the CoderDojo club model on a whiteboard together

Image Prompt (This is Panel 05. Do not include the panel number in the image.) Please generate a 16:9 image in the same style depicting panel 5 of 8. Keep James and Bill consistent with prior panels. The scene shows James and Bill standing together at a whiteboard headed "OUR CLUB MODEL," both holding markers, both mid-sketch. The whiteboard shows three linked circles of simple stick-figure icons labeled "YOUNG PEOPLE BUILD PROJECTS," "MENTORS GUIDE," and "PEERS TEACH PEERS," arranged around a house-shaped icon labeled "VOLUNTEER-RUN FREE CLUB," plus a short list: an open-door icon labeled "OPEN DOOR," a euro symbol crossed out labeled "ZERO FEE," and a small circle of figures labeled "SHARING." A handful of students sit at a table in the foreground with notebooks and a laptop, watching. Wall posters read "CODE CREATE CHANGE" and "Everyone Can Code." A doorway shows more students passing in a hallway. Color palette: clean whiteboard blues against warm classroom tones. Emotional tone: clarity, two people converging on the same idea. Six visual details: the three linked stick-figure circles, the house-shaped "volunteer-run free club" icon, the crossed-out euro symbol, the open-door icon, the students watching from the table, the doorway with passing students. Generate the image immediately without asking clarifying questions.

Together they drew out the shape of it: young people building their own projects, mentors guiding rather than lecturing, and — the part that mattered most — peers teaching peers, the same habit James had never stopped doing since the iPod hack. It would run on volunteers. It would never charge a fee. "From day one we decided that it would all be free," James said later, "money can often cause headaches and poison things." The whiteboard sketch needed a name, and it needed a first real session.

Panel 6: The First Dojo

A packed classroom holds CoderDojo's first large session in Cork

Image Prompt (This is Panel 06. Do not include the panel number in the image.) Please generate a 16:9 image in the same style depicting panel 6 of 8. Keep James and Bill consistent with prior panels. The scene shows a large room packed with rows of teenagers at laptops, several adult volunteer mentors in name tags circulating between tables, far more people than any previous panel. A whiteboard reads "CORK, IRELAND / 2011 — WELCOME TO OUR FIRST LARGE SESSION!" beside a small stick-figure circle diagram, and a second sign reads "TODAY'S PLAN: WELCOME, INTRO, CODING TIME, BREAK, SHOW & TELL, NEXT STEPS." Bill stands near the whiteboard addressing the room warmly with open hands, dressed in his dark suit. In the foreground, James leans over a laptop helping two younger students, one of whom has a Super-Mario-style game visible on her screen. Wall posters read "CODE CREATE CHANGE," "Everyone Can Code," and a sign reading "GROWING OUR CLUB." Windows show Cork's skyline. Color palette: bright, full, energetic classroom light. Emotional tone: the buzz of a first big turnout succeeding. Six visual details: the "welcome to our first large session" whiteboard, the "today's plan" agenda sign, the circulating mentors with name tags, the girl's game project on her laptop, the packed rows of laptops, the Cork skyline through the window. Generate the image immediately without asking clarifying questions.

On 23 July 2011, the plan became real: the first official CoderDojo session opened at the National Software Centre in Cork, with volunteer mentors circulating among rows of laptops and a simple agenda on the whiteboard — welcome, coding time, a break, and a show-and-tell at the end. James kept doing exactly what he'd always done, leaning in to help one student at a time, except now dozens of other mentors were doing the same thing beside him, all for free.

Panel 7: The Idea Travels

A world map shows CoderDojo sessions springing up on every continent

Image Prompt (This is Panel 07. Do not include the panel number in the image.) Please generate a 16:9 image in the same style depicting panel 7 of 8. Keep James and Bill consistent with prior panels. The composition is a montage: a large central panel shows the same Cork classroom from panel 6 with James, Bill, and students at laptops, set against a faded world map background with dotted travel lines connecting location pins across Europe, the Middle East, Africa, South America, and South Asia. Six smaller vignette panels surround it, each showing a different local coding session: a boy, a teenage girl, and an elderly man at a laptop; a different trio around a laptop with a grandmother present; a South Asian family of three at a laptop in a home setting; two boys with a mentor wearing a taqiyah cap; an African father and son at a laptop; an Andean family of three in a mountain village setting. Each vignette includes a stack of papers labeled "mentor, plan, resources, outreach, sustain." Color palette: muted map greens and blues behind warm, varied vignette lighting. Emotional tone: a single idea multiplying across cultures and continents. Six visual details: the dotted travel lines on the map, the location pins, the stacked "mentor plan resources" papers repeated in each vignette, the varied home settings, the varied family groupings, the central Cork classroom anchoring the montage. Generate the image immediately without asking clarifying questions.

The idea didn't stay in Cork. Within about a year, Dojos had opened across Ireland, then in London, then in San Francisco — each one run the same simple way: local volunteers, a free venue, and kids teaching kids under a mentor's light touch. "I really never imagined how popular it would be, or how fast it would grow," James admitted. By the time CoderDojo merged with the Raspberry Pi Foundation in 2017, more than 1,250 Dojos were running in roughly 69 countries.

Panel 8: Each One Teach One, Everywhere

Flags from many nations hang above a diverse group of students coding together

Image Prompt (This is Panel 08. Do not include the panel number in the image.) Please generate a 16:9 image in the same style depicting panel 8 of 8. Keep the mentor consistent with prior panels. The scene shows a classroom years after the founding, decorated with a row of national flags — Ireland, India, Brazil, South Africa, Japan, Saudi Arabia, Kenya, Greece, Italy, Vietnam, the United States, Russia, and others — hanging overhead. A diverse group of teenagers, including a girl wearing a hijab, work together at laptops in the foreground beside a sign reading "FREE ACCESS OPEN TO ALL." A whiteboard behind them reads "EACH ONE TEACH ONE" with bullet points "SHARE KNOWLEDGE," "BUILD TOGETHER," "OPEN TO ALL," and a small circular stick-figure diagram; a nearby poster reads "EVERYONE EVERYWHERE WELCOME." To the right, two men stand together watching the room with quiet satisfaction: Bill Liao, still recognizable in his dark suit and glasses, and James Whelton, now an adult, in a casual sweater with arms crossed. Wall posters read "CODE CREATE CHANGE" and "OUR COMMUNITY OUR FUTURE." Color palette: warm, celebratory, full of color from the flags. Emotional tone: pride at a small idea's global reach. Six visual details: the row of national flags, the "each one teach one" whiteboard, the "free access open to all" sign, the diverse group of students, the "everyone everywhere welcome" poster, the two founders watching together. Generate the image immediately without asking clarifying questions.

Years on, a Dojo session looks the same in spirit wherever it happens: free, volunteer-run, and full of kids explaining things to other kids. The flags change from room to room, but the whiteboard rule doesn't — share knowledge, build together, open to all. James and Bill, who once sketched the whole idea on a notepad at a Cork startup event, still recognize their own club model in every one of the thousands of Dojos that grew from it.

Epilogue – What Made This Different?

CoderDojo didn't start with a grant, a curriculum, or a nonprofit filing. It started with one teenager who couldn't stop teaching what he'd just learned, and one mentor who recognized that instinct was worth structuring rather than replacing. The free, no-fee, volunteer-run, "each one teach one" model that resulted turned out to be exactly repeatable — which is the only reason it could spread from a single Cork classroom to thousands of rooms around the world.

Challenge How Whelton and Liao Responded Lesson for Today
A teenager had teaching instinct and local fame but no organization or funding know-how Paired with an experienced entrepreneur-mentor who supplied structure and outside credibility while James kept teaching Great clubs often need both a passionate teacher and a resourceful organizer — don't wait for one person to be both
An after-school hobby could easily have stayed one school's lunchtime club Decided from day one that every Dojo would always be free Removing the cost barrier is often the single biggest thing a club can do to reach every kid, not just the ones who can pay
One founder cannot personally run a thousand clubs Published a simple, repeatable model — volunteers, a free venue, "One Rule: Be Cool" — that any group of parents or mentors could copy without asking permission A club that scales is a club with a documented, repeatable model, not a single irreplaceable leader
A youth-led charity had big ambitions but limited institutional backing Merged with the Raspberry Pi Foundation in 2017 while keeping CoderDojo's own name, brand, and volunteer network intact Partnering with a larger, mission-aligned organization can extend a grassroots idea's reach without erasing what made it work

Call to Action

You don't need permission, funding, or a finished plan to start what James Whelton started — you need one person willing to teach whoever walks up and asks. Write down what works, keep it free, and let the kids who learn from you become the ones teaching the next group in the room.
