Code

styles/70s-poster/kit.js → Groovy: PAL (palettes acid, sunset, submarine), sunburst (full-bleed rays), rings (wavy rings), wavy(pts, amp, freq, phase) (the outline breathes), shape(g, pts, fill, { ink, width, echoes, echoStep }) (flat shape with an ink outline and echoes), ellipse, line, melt (text that drips and melts into drops) and path. Typeface: Shrikhand (fonts/Shrikhand-latin.woff2, OFL).

Style rules

• Flat and acid: no gradients or shadows. Every color next to its complement (orange/magenta/acid green/violet/yellow). Very dark violet ink, never black.
• Thick outline on everything that is a figure, and echoes in 1–2 colors on the protagonist.
• Everything waves, nothing jitters: deformations are smooth sines of t (wavy), not noise.
• Motion on the beat: side-to-side sway per bar, squash on every beat (Motion.pulse).
• Letters: Shrikhand, with outline and echo. When they melt, round drops fall (a few bells), not a noise of spikes.
• Background always moving (spinning rays, waving rings), but less saturated than the figure.

Style checklist

• Any gradient, soft shadow or pure black?
• Do the figures have an ink outline and the protagonist echoes?
• Does the melt read as drops of paint?
• Does the figure stand out from the background (size, contrast, echoes)?

Lessons

• 2026-09-24 · exquisite-corpse · A random column-by-column drip profile reads as spikes: drops = a few bells over a smooth fall (now in melt).
• 2026-09-24 · exquisite-corpse · A chorus of small figures on the offbeat (Motion.pulse(t, bpm, 0.25)) and ornaments spinning in the corners add density without stealing the lead.
