FR-AI / ANALYSISWhy it is worth attention
It showcases cutting-edge WebGPU rendering (three.js), real-time physics (box3d.js), and video export via WebCodecs, all in a playful, shareable toy builder.
Who it is for
- Web developers exploring three.js and WebGPU
- Game developers prototyping physics-based interactions
- Creative coders and hobbyists making virtual toys
- Educators demonstrating 3D mechanics and physics
Use cases
- Building and testing wooden toy mechanisms virtually
- Creating shareable interactive 3D models with encoded URLs
- Learning and experimenting with three.js WebGPU rendering
- Prototyping simple physics-based games or puzzles
Strengths
- Uses real-time WebGPU renderer with GTAO for high-quality visuals
- Physics engine (box3d.js) enables realistic movement and collisions
- Built-in 5-second video export and URL sharing of toy designs
- LocalStorage saves progress automatically during building
Considerations
- Requires a modern browser supporting WebGPU
- Limited to a wooden block aesthetic with no custom materials
- No multiplayer or collaborative building features
README quick start
Toys
A little toy maker. Snap wooden pieces together, make parts spin, then switch to Play and watch your toys come alive.

How to play
Build — Drag pieces from the palette onto the floor or onto your toy. Click a piece to select it: drag the orange handles to resize, S to make it spin, drag the teal pin to move the spin axis, D to duplicate onto the opposite side, delete to remove. Drag pieces to re-attach them, or drag the base piece to move the whole toy.
Play — space. Toys drop onto the floor and their motors start. Click a toy to focus the camera, R to reset. The eye in the toys list picks who's on stage.
Share — Records a five second clip and copies a link with the toys encoded in the URL. Everything is also saved to localStorage as you build.
