This is a very simple experimental use of WASM.
If you'd like to clone/fork & play with it locally, you'll need to run a local webserver using dist/ as your root, as the fetch API doesn't support file:// refs.
I used https://mbebenita.github.io/WasmExplorer/ to compile from C to WAST, then from WAST to a WASM binary. Current plans are to get Emscripten set up to have a nicer build flow.
