Since Gemini 4 Carbon launched, people have been showing what they built with it, from a browser game to a CUDA-coded meadow.

Google's own Pelican Quest is an open-world 3D browser game where you ride around its Mountain View campus as a pelican on a GBike. It was made with Carbon and /swarm in Google Antigravity: subagents modeled and rigged the 3D assets in Blender, then Carbon coded the game in Three.js with WebGL2 shaders, procedural audio and an original Lyria soundtrack. It is playable in Google AI Studio.

Glitter Gal coded a meadow of wildflowers and grass blades from scratch in CUDA and C++ with Carbon, with the wind synthesized to match every gust. Another builder started from a single reference image to recreate a 19th-century Parisian optics lab with brass and glass instruments you can test and tune, and another turned scattered public datasets into interactive tools with live 3D visuals.

Google also had Carbon build an interactive 3D visualizer in Antigravity from a 2026 study on knitted textile mechanics, tracking individual fibers under tension.
