JellyDazzle Command Panel

Hover any tile to see it move and shift colour. Thumbnails are one fixed palette — the app cycles 180 schemes, so judge shape here, not colour.

How a frame is built. Up to four layers run at once, bottom to top: a GROUND fills the screen, a FIELD covers most of it with gaps, a FIGURE drops distinct shapes over that, and a SPARK adds glints. They blend by brightness, so dark parts of an upper layer let the one below show through. Each layer takes a turn of its own length, then a new routine is drawn from the bag and fades in — timing is random by design, never a fixed loop. An accumulator doesn't repaint each frame: it clears once and keeps drawing onto itself for its whole turn, which is how the line-art builds up.

Your weights drive the bag. ▲▲ puts a routine in the bag several times, ▼▼ puts it in once and rarely — it still shows up, just not often. Nothing is discarded.
