I'll be one of the Guests of Honor at Penguicon 2010, and they asked me if I'd like to provide some artwork for them. Happy to oblige, today I knocked down seven penguin pictures for the various flavors of badges. If you happen to be on staff, a colored version of the penguin to the right will grace your badge. That panicked look on your face? That's what you get when you're running a convention, and all you have is a hammer and duct tape.
Panelist Penguin, ConCom Penguin, and Attendee Penguin all look much more self-assured.
