I ♥ CMU undergrads. It's not like it's a particularly stunning rendering of it, but the fact that someone after a probably already long 212 assignment (one that happens to allow 2d graphics output) would go to all the effort of implementing, above and beyond the requirements of the assignment, fixpoint arithmetic cosine and parse some crazy file format so that they can get a rotating 3d utah teapot --- well, it just warms my heart, it does.
