I was having difficulty understanding it, but the explanation and diagrams at 2:47 are what finally clicked it for me.
Very interesting stuff. Also, a toroidal void is what I call taking a dump after eating some donuts.

I would have thought Toroidal Void would be a band name, they could open for The Spherical Cows.
