Originally, I was trying to figure out how to get a trillion with a circular table, that looked like a vortex from the top. But, since I don't usually do radial symmetry, and I'm too lazy to use the "rotate" feature, I kept having to turn my head. Hence, the name. Works in materials from feldspar to rutile (RI = 1.52 - 2.62) with no changes. Suggested size = 6-10 mm
