`Drivin Me Crazy' was partly inspired by the theory of moduli spaces of polygons with fixed angles. I first learned about this theory from Bill Thurston, and there is paper by Ghys and Bavard on the topic. I'm not sure who originated the theory. The example relevant to the game is the space of convex hexagons whose interior angles are all 120 degrees. Call these ``pseudoregular'' hexagons. (The regular hexagon is the archtypical example.) Given the right coordinates, the space of pseudoregular hexagons is just a convex cone C of 4-dimensional Euclidean space. On C there is a quadratic form of type (3,1) whose diagonal part is the area function. Equipped with this form C becomes a cone in Minkowski space, the space familiar from special relativity. The set of unit length vectors - that is, unit area pseudoregular hexagons - in C has a natural interpretation as a subset of 3-dimensional hyperbolic space. `Drivin Me Crazy' is set up in such a way that the inner part of the expanding hexagon is pseudoregular and has unit area. So, when you play ``Drivin Me Crazy'', you are steering around a room in hyperbolic space, trying not to hit the walls.
