Non-euclidean virtual reality

Try at h3.hypernom.com and h2xe.hypernom.com. Controls: wasd rotates, arrow keys move, numbers change decoration, c changes colours. Also works on smartphones - touch the screen to move forwards.
If you have a Vive, you may be able to get this to work on Firefox - press v then enter to get graphics showing on the headset. No guarantees though, WebVR is a fast moving target.
This is joint work with Vi Hart, Andrea Hawksley and Sabetta Matsumoto.
