Finally, http://Karts.com is live! 🏎️ I still can’t quite believe I built a 3D kart racing game. Come give it a try! 😄 I created the characters with Nano Banana and ChatGPT, turned them into 3D models with Tripo3D, built the tracks with Claude Opus 5.5 and Blender, and brought it all together in Three.js. Thirteen of the 20 cities are places I’ve visited. I poured my memories of them into the tracks, and I hope you’ll enjoy the scenery as much as the racing. #GameDev #ThreeJS
