A ball with gravity loose in a Metroid room — tile collision, bomb jumps, and a dithered lamp that is the only thing lighting the cave.

Three interfering sine waves crushed to one bit through a 4×4 Bayer matrix, drawn at a fifth scale and blown up with smoothing off.

Two chemicals on a grid, one eating the other. Nobody drew the coral — it is four constants arguing, quantised through the same Bayer matrix.

Sand, water and stone, one rule per grain. No bodies, no forces — just cells checking what is underneath them, bottom row first.

Blur a layer of circles, then crush the alpha channel with a colour matrix until they fuse. No maths, just a filter behaving badly on purpose.

The honest version of the piece above — sample a scalar field on a grid, then trace the line where it crosses a threshold. Three thresholds, so it reads as a contour map.

Three chains that never store a velocity. Move a point and it gains momentum for free, because the physics reads it from where the point used to be.

Two quarter-arcs per cell, one of two rotations. Neighbours join up and the whole grid reads as continuous loops nobody drew.

Four hundred particles reading their heading from a drifting noise field. Trails are erased rather than painted over, so it floats on any background.

The icon at the top of every page. Seventeen gradient rows, each sweeping at its own phase, plus film grain. One uniform buffer, no textures.
