Jelly Sheet

More from mrdoob.github.io →

An interactive 3D WebGL demo by mrdoob for Codevember 2026 simulating a draggable, glossy plastic jelly sheet folding onto a floor, with rendering settings.

What HN thinks

A delightful wobbly jelly toy, immediately buried under a firm, unwobbly argument about whether vibe coding counts as Codevember.

Vibe coding undermines creative challenges
Some feel AI-generated entries clash with the spirit of Codevember, game jams and similar challenges meant to showcase human skill and fun.
Creativity lies in the idea
Others argue directing an AI is still creative, likening it to photography or project leadership, and note Mr Doob's track record with Three.js.
Fun, squishy, but heavy
Many simply enjoyed the toy, while some reported lag as it accumulates and WebGL failures on certain mobile browsers.

Consensus: Most agree the demo is charming and satisfying to play with; there is no consensus on whether using AI for it diminishes the work.
