Hacker Con Badges.

Eliot Phillips of RobotSkirts and Hack-A-Day uploaded his neat collection of hacker convention badges (like one that looks like the ghost from Pac-Man).

This one above is the badge for ToorCon 2007 Seattle – it looks like the chocolate from Willy Wonka (the invite is the "Golden Ticket").
