Build a 3D street racer in Unity with AI and score it with a Lyria song
In one day AI built a rainy neon-city racer with six drivable cars, physics, AI rivals and a cockpit view. Claude and Gemini wrote the code and shaders, Google Flow made concept art, Tripo the 3D models, Blender fit them in, and Lyria made the teaser song.

What they did
In one day AI built a rainy neon-city racer with six drivable cars, physics, AI rivals and a cockpit view. Claude and Gemini wrote the code and shaders, Google Flow made concept art, Tripo the 3D models, Blender fit them in, and Lyria made the teaser song.
Result (as claimed)
A playable racer plus teaser; next time he'd split work across parallel subagents.
Tools they used
Cost: Tripo: free plan, paid from $20/mo. Checked 2026-10-14.
Set it up
Write a one-page brief
Describe the app in plain words: who it is for, the 3 core screens or actions, and what "done" looks like.
Start the project with your agent
Open Claude and paste the brief. Ask it to propose a stack and a file plan before writing code.
Build one slice at a time
Ship the smallest working flow first, run it, then add features one by one. Commit after each working step.
Test it like a user
Click through on desktop and phone. Ask the agent to add basic tests and fix anything that breaks.
Check security and ship
Keep keys in environment variables, check auth and database rules, then deploy and share the link.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like). 2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure. 3.
