Here's a variation on the Knight's Tour that I made up. If you're on a red square, you move like a knight. But if you're on a black square, you move by picking up your piece, rotating the board some multiple of 90degrees, and then dropping your guy back down. This variation seems more difficult to me than the original, maybe because the travelling salesman graph is now directed. Let me know if you came up with some elegant way to solve it.
