This is intended to be an orthographic projection of a stereographic projection from S5 (the five-dimensional surface of a sphere in six-dimensional space) into E5 (flat five-space) of the cartesian product S2 × S2, a kind of torus. The colors represent the three suppressed dimensions.
I did not expect it to look like this, but then, I did not know what to expect.
One of these days I’ll try it on S1 × S2 and see if that looks any more familiar.
Perhaps the asymmetry reflects a flaw in random number generation.
