// Hi! I think you’re going to like this VR stuff :)
// This index.html file created by Jeff Nusz / http://custom-logic.com
// refactored and commented by Stewart Smith / http://stewartsmith.io
// because this stuff is fun and you can learn it with us!
// The real heart of this is VRController.js -- check it out!
// Does this browser support the WebVR API?
// Here’s how to download and configure one that does:
// https://webvr.rocks
WEBVR.checkAvailability().catch( function( message ){

// not necessary, but we’re going to attach a “head” to the camera that casts
// a shadow so you can see evidence of your own presence.
