The Hugo Awards — one of science fiction's leading honors — have a beautiful trophy, a silver, streamlined rocket-ship. What they don't have is a logo that can be used on things like anthologies of Hugo-winning fiction, the spines of Hugo-winning books, and so on.
So they're holding a contest to design a Hugo logo. You have to use the rocket-ship, and you get $500, a ticket to the Worldcon and a signed Neil Gaiman book if you win. Judges are Neil Gaiman (3 time Hugo Award-winning author), Chip Kidd (graphic designer, author, editor), Geri Sullivan (SF Fan and graphic designer pro) and Irene Gallo (art-director for Tor).
