Oculus Rift GUI

For simple WebGL applications based on Three.js the Google's Chrome Experiment DAT.GUI is a good choice to render a minimal user interface, but there is no simple and reliable way to render DAT.GUI inside the WebGL scene. Oculus Rift Applications need to render the user interface inside the scene to display the GUI for both eyes and they need two mouse cursors. This experiment demonstrates how to render a GUI for Oculus Rift.
