Back in the day, I made a few levels for Marathon, this great Mac game that was basically the Mac’s Doom equivelent. (better than doom, IMHO). Of course, when quake came out, Marathon was dust in it’s tracks, but Bungie went on to make some other kick ass shit–but all that’s beside the point.
This is what I meant to link. Funny as hell, and themushroom.com is well worth checking out, even if the design sucks ass. (their “Apple releases iLamp” article is also quite humorous.)
