Draw app icons with Opus 5.5 using JS + Canvas instead of SVG — one-line prompt trick
dotey · x · 2026-09-27
@dotey shares a trick for designing app icons with Opus 5.5: since the model can draw video frame-by-frame with JavaScript + Canvas, it can also draw icons the same way. The key is prompting for "draw with JS on canvas" rather than SVG — SVG output quality falls short. First attempt produced a clean, colorful icon exceeding expectations from a one-line prompt; results can also be exported as SVG, unlike bitmap outputs from image generators.
