In celebration of all this Portal excitement, I figure I can get away with inflic... offering my Portal maps for people to play if they're looking for some new challenges.
Shmitzchamber - Difficult, largely trajectory-based puzzles.
Accident Prone - A shorter set of puzzles using portal mechanics not really explored in the first game.
Very good maps, just fiendishly difficult since the very first puzzle dumps you straight in it with no tutoring.
