As Peng said, I was thinking of a contest using JavaScript and 1024 instead of 512 characters. If we want to be kind of evil, we could even force the code to pass JSLint, requiring them to have readable whitespace and everything.

C macros are neat, but I feel the creation of unreadable, maximally compressed programs distracts from the goal.
