Build an interactive 3D jelly gummy bear in the browser that I can grab, squish, stretch and fling with my mouse or finger. Use real soft-body physics so it wobbles, jiggles and slowly settles, and keeps its volume when squashed. Make it look edible: translucent, glossy, light glowing through it, a soft shadow on a clean studio backdrop. Add a few toys: drop it from above, poke it, switch flavours (colours), and a firmness slider. Make it feel deeply satisfying to play with. Deliver one working page, no prerecorded video.
