ffutures | Flatland names

I'm working on characters for the Flatland game I'll be running at Dragonmeet and want a few names. All characters will have some knowledge of Forbidden Mathematics and the Third Dimension, so far I have

Rhombus, near-equilateral triangle and immortal (yes, I know the name is all wrong for a triangle) who for various reasons can percieve the third dimension.

Albert Square (name stolen from Stewart's "Flatterland"), narrator of Flatland

Ellery Quin, five-sided detective and mathematician.

I could also use Professor Hex, one of the sample characters in the rules, if I change his stats a little, but I'd prefer someone new. Any suggestions? Preferably names that are funny...
