Thanks for sharing! We're Supermedium from YC W18. We built Supercraft to easily allow people to intuitively build their own worlds with their hands in VR that can be shared with just a URL.

It also allows WebVR and A-Frame developers to easily create good looking, consistent 3D assets that are performant and really low file size, particularly for A-Frame. Here's an example making a simple shooter game in a few lines of HTML with Supercraft assets: https://github.com/supermedium/supercraft-shooter
