Google for Developers shares Three.js demos and a Gemini 4 Argon Rubik's cube project

Google for Developers posted on X a Three.js demo built entirely from code with no assets, according to a post linking to x.com.

In a second post the same account shared a project in which Gemini 4 Argon, running in Antigravity, built the full project, from modeling robot arms in Blender to a 3D simulation in Three.js. Gemini then used the Interactions API to solve a Rubik's cube, the post says, with zero hints and 16 tool calls available to test moves.

The posts are the account's only sources for these claims in the reports reviewed; neither post is independently verified.
