About This Poster

The chapter's comparison table lists four abstract properties in text — this poster shows what each mode actually looks like on a real keyboard: a slow shifting rainbow versus an instant flash on keypress.

How to Use

• Explore — click a mode to see how it's triggered and what it's used for.
• Quiz Me — test whether you can match a lighting behavior to the right mode.
• Edit mode — open main.html?edit=true to drag the zone corner handles and calibrate boundaries once the poster image is generated.

Zones

1. Ambient Lighting Mode — a continuous timer-driven animation
2. Reactive Lighting — a change triggered by a key event
