Oh, I don’t know about that 1 pixel business. The problem with the
surface as it’s currently written, is that it flip-flops between
convex and concave every at every triangle. But if you ignore the
triangles and spin the surface around a bit, it really looks like
an inner torus surface oriented diagonally. We know how to do that
without making a lumpy mess of it. The challenge is in getting
a diamond shaped slice of torus instead of a rectangular slice.

I think the key difference is the twisted nature of this surface. I think the
twist makes it impossible to partition the surface into polygons without having
a mix of convex and concave seams. I’d like to be proven wrong.
I don’t have one of the pieces handy, I’ll have to look at some tonight, at
home.
