# Cube

> Taffy pack: a puzzle cube of eight soft candy blocks in rose, sky, butter, lilac and mint round a lilac band. It fidgets on a loop: the top layer twists a quarter, then the bottom the other way, then each twists back, lifting a hair and landing with a click. A tap bursts the blocks apart and snaps them back together. Raymarched in WebGL.
