Show HN: Live webcam metal pin toy simulation powered by WebGPU depth estimation

Remember those metal pin art toys you'd press your face or hands into as a kid? You can now use your webcam to create a virtual pin art display in real time! Wave, make faces, or get creative - the pins will follow your every move.

This application creates a virtual pin art display using your webcam and real-time depth estimation. The app uses the Depth-Anything-V2-small model with HuggingFace's transformers.js to generate depth maps from webcam input and simulates a 3D pin art board using Three.js.
