Paint a little living world with ten materials: pour water, grow ferns, float oil, quench lava and watch clouds form. Four starter scenes, three discoveries, undo, keyboard and touch controls, device-local saves and original GPT terrarium artwork. Compact JavaScript adaptation of Sandspiel material rules; local discrete simulation without the upstream pressure solver or online services. Source: https://github.com/MaxBittker/sandspiel (MIT).
