Example for a very simple GUI built using wgpu
Simply run RUST_LOG=info cargo run to run the application and a simple GUI will open up, which you can interact with.
To build it for the web (you need a browser that supports WebGPU!), run wasm-pack build --dev --target web --out-name wasm --out-dir ./static and then python3 -m http.server to serve it at http://localhost:8000/index.html.
