Yeah, you might enjoy:

(p nor q) nor ((p nor p) nor (q nor q))

Remember that nor returns true only if both arguments are false. So, we want to return true if the inputs aren't both false or both true. The former is simply p nor q and the latter is (not p) nor (not q) and we use the expansion of not.
