Starfield, plasma & fire

A full-screen canvas running one of three animated effects, each drawn cell by cell in truecolor: a flying starfield, a sinusoidal plasma field, and a bottom-up fire. Press 1, 2, or 3 to pick one, or Space to cycle.

There is no image and no shader here — every cell's colour is computed per frame and handed to the engine as a #rrggbb value, which then downsamples it to whatever the terminal actually supports (256 colours, 16, or monochrome). So this doubles as a live stress test of two things at once: the colour engine, and the damage-diff renderer that repaints only the cells that changed.
