Remember that xkcd "Tetris Hell?"

I thought there was already a whole thread devoted to the game version of that comic that I once saw here. But apparently it was just me making one post in a very obscure thread about the comic. And calling this old off a post I made makes me feel pretty narcissistic, but I'm going to do it anyway. Just wish I could remember how I found it...
