RiftSketch is an HTML5 live-coding environment for the Oculus Rift based on troffmo5's OculusStreetView.
It lets you code a "sketch" in JavaScript, using ThreeJS, and the scene in front of you updates immediately as you code.
RiftSketch requires an Oculus Rift headset and an external tracker application developed by lazydodo.
