Balti Walk
One prompt, six models, six walkable Ladypool Road scenes. Same street, different builds.
Three.js in every version. WASD plus mouse to walk. Pick one and take a walk.
The prompt each model received
“Create a small but realistic world resembling the Balti Triangle in Birmingham (specifically Ladypool Road) that I can walk around. Use JavaScript.”
