This program generates organic-looking clusters by having shapes randomly jostle and sort themselves into position. Sometimes it takes a long time to reach equilibrium, so the preview may capture before the final equilibrium position. The clusters vary according to:

Palette: 12 curated palettes and one random.
Shape: Mixed or Boogers.
Mode: Circles, Brush, Crystals, Evil Boogers!

You can navigate the short story included in Evil Boogers! mode using the right and left arrow keys.

I could not get this to run on my Android phone to save my life, so please check for compatibility before you mint. WEBGL makes me want to eat my own head.
