Show HN: Simple physics WebXR audio experiment

A quick experiment to play around with the WebXR API (currently working only in Chrome Android 81+).

It's impressive how it is now possible to build full-blown AR apps straight into the browser, using just frontend stack. We built this using three.js in just a few days for fun, and the whole website with 3d models and sounds is ~15mb.
