I'd like to see at least two things. The first is a WWII style poster, with a lantern-jawed hacker looking off into the distance while bombers fly overhead. He's wearing sensible overalls and a hard hat, and he has the Camel in his hand. It's rendered in the simple, yet strong strokes like you'll see on Active State logos.

The caption says, "Perl Monks want YOU to use strict and -w."
For the second, just something nice that says 'PSI::ESP' on it. A nice sticker would be okay.
