Interestingly enough, this variant of postergasm was what got me onto the idea in a big way. I have a set of posters I'm planning on putting up around campus just before (the morning of, if I can time it right) enrollment*, hopefully in all the thoroughfares where all the first-years are processed so the posters get a lot of attention. Some inspired by cram's, some my own invention. I was originally just having an email account and url on each poster, so interested people could read about postergasm, but turning it into its own little site with scoring could be interesting.
I'll process and upload mine in the morning for perusal/criticism, as right now they're in not-so-easy-to-view .pages form.

. As I mentioned, some of these have been shamelessly copied from other folks.
