Exhibit No. 014 · Apps
A 3D brick editor like the one that stole Gemini 3 launch day: place, stack, rotate and recolour bricks on a baseplate.
> Create a 3D LEGO-style brick editor in a single HTML file using Three.js. Let me place, remove, rotate and recolor bricks of different sizes on a baseplate with snapping, an orbit camera, and a clean UI.Spatial logic and editor UX: grid snapping, stacking, picking with the mouse, undo and an orbit camera.

Prompt wording adapted from the original.
●●●
One attempt per test, with no edits after running. Where a first attempt didn’t work, the test was answered once more and the exhibit says so; answers that still don’t work are not shown. Run inside a Claude Code agent session, which includes its own system prompt, rather than the raw API.
Save the answer as a .html file and open it in a browser to compare it with the one above.
