What this shows

A matte clay Bot sphere head on a violet stage — warm key light, blue-violet rim, and pink fill. With no input for a couple of seconds it acts curious on its own: glances down toward a desk line, lifts to meet the viewer, blinks, and varies timing with spring-smoothed motion. Move the pointer over the stage and the head and slanted eyes track with lag; a fast sweep startles; click or Space gives a happy squint and hop; press-and-hold turns suspicious with narrowed eyes and a tiny tremble; drag in circles makes it dizzy until release; leaving the stage makes it look after the pointer, wink, then return to idle. A caption names the mood. Reduced motion softens amplitude and skips spin.

How it was made

A self-contained three.js WebGL demo in the iframe (CDN import map, single renderer pass). Procedural idle targets and damped springs drive head and eye transforms; eye meshes scale and rotate for expressions. There is no video on this page.
