I really like this idea. I would like to add a vote in favour of having our perlmonks identity on them (I picked one I'm happy to wear - sorry about those who didn't ;-))

I don't like obfuscated code, so I'm not in favour of that. I like elegant code and clever code, code that isn't what a beginner would write, but not obfuscated code, I think it's silly. Not that I'm saying I wouldn't buy one with obfuscated code, just that I find it boring :-(

Baldrick, you wouldn't see a subtle plan if it painted itself purple and danced naked on top of a harpsichord, singing "Subtle plans are here again!"
