Contributors Wanted: WASM showcase for the gcode crate

I've recently been giving the gcode crate a makeover and was thinking it'd be cool if we had an online showcase built on top of the library.

I've done a couple web apps in my time, but they were done with Django, React.JS or Angular. If anyone has experience writing WASM apps in Rust and would be interested in helping out, let me know by commenting on the issue below!
