Image Brief: Acrylic Base

Written for a text-to-image model because no suitably licensed photograph of a Moving Rainbow acrylic base exists in this repo or any sibling repo. The find_part_image.py search for "acrylic base" and "plexiglass" returned only unrelated diagram files.

Delete this file and remove the placeholder from purchasing-guide/index.md once a real photo or generated image is in place.

Prompt

A rectangular sheet of clear 3mm acrylic, roughly 4 by 8 inches, lying flat on a plain white seamless background. A small white solderless breadboard is mounted on top of it, and a short strip of addressable RGB LEDs runs along the front long edge of the acrylic. The acrylic's cut edges catch the light and glow faintly. Soft, even product-photography lighting with no harsh shadows. Shot from a low three-quarter angle so the thickness of the sheet is visible. The assembly fills roughly 70% of the frame. Sharp focus throughout, high detail, no text overlay, no watermark, no hands, no packaging.

Physical details that must be right

A teacher will use this image to understand what to cut and how it goes together, so these features carry the meaning:

  • Size: roughly 4" × 8" (100mm × 200mm), 3mm thick
  • Material: clear transparent acrylic (not frosted, not colored), with visible edge thickness so the reader can judge the 3mm
  • Breadboard: half-size 400-tie-point white breadboard, adhesive-mounted flat on the acrylic, positioned toward the back half of the sheet
  • LED strip: a short WS2812B strip along the front long edge, unlit or only faintly lit — a fully lit strip blows out the exposure and hides the base, which is the actual subject
  • Distinguishing marks: the protective film is fully peeled; edges are cleanly cut, not snapped

What it must not look like

  • Not a finished commercial product enclosure. This is a flat mounting plate, not a case with walls or a lid. Anything that reads as an injection- molded box sends readers looking for a product that does not exist.
  • Not frosted or white acrylic. The transparency is the point — it is why the edge glows.
  • Not thick cast acrylic. A 10mm slab looks like a display block and costs several times as much.
  • The LED strip must not dominate. The base is the subject; other sections of the guide already show the strip on its own.

Aspect ratio and size

  • Aspect ratio: 4:3 landscape
  • Target: at least 1000px on the long edge
