Whirly

Bloop pack critter: a tangerine cyclops with one big googly eye, a four-panel propeller beanie and little feet dangling below. It hovers with the blades whirring; every few seconds the propeller sputters, it sinks with its eye wide and its mouth in an O, then the blades catch and it zooms back up with a spin. A tap revs the propeller. Raymarched in WebGL, six palettes.
