3-sphere explorer project (1)

I'm writing a browser demo/game using html5/webgl, in which the player travels on "3-spheres" (curved space. fly in any direction and end up where you started) linked by spherical portals. 

Future blog posts might describe this and more in tedious detail. 

The project (so far) can be found at https://filbs111.github.io/3sphere-explorer/

Options include drawing regular polytopes (5-, 8-, 16-, 12-, 120-, 600-cells), duocylinders, and even lines of cubes.

TODO add fun.
