RiftSketch is a web-based live coding environment for Virtual Reality.

It lets you code a "sketch" in JavaScript, using ThreeJS, while the world around you changes immediately as you code.

It's quite a niche application since you need to have a VR HMD, be a JavaScript programmer and be sufficiently familiar with Three.js but if you meet that criteria it's surprisingly fun and engaging!

• Live-coding with real-time scene updates
• Collaborative coding. Share your creations.
• Convenient keyboard shortcuts
• Leap motion support
• Webcam pass-through

If you happen to have a VR headset and you want to try it out yourself, download a developer build of Firefox or Chrome that includes the WebVR APIs from MozVR or the Chrome dev build share and visit http://brian.peiris.io/RiftSketch/

RiftSketch should also work on mobile phones, with Google Cardboard. Currently, Firefox Nightly for Android and Chrome Dev for Android work the best. Bug reports are welcome!
