Voxel koi garden: day and night pond with arched bridges

I had early access to Gemini 4 Hydrogen, and it was an amazing experience. I am so glad this model is finally out to the public for everyone to enjoy, not just Ultra subscribers. I am still exploring the possibilities and looking forward to seeing what people do with this model.

In this demo, I used the model's speed to build the Koi Garden. Instead of doing everything in one prompt, I built the project in a modular design: each module handled a section, and I did 20 modules across 20 prompts. Each prompt took between 90 and 270 seconds to finish, and all of this inside the Gemini app, not Antigravity, not Google AI Studio 😃
