Project: Rooftop is now accepting entries for the second annual costume contest: Fights, Flights & Tights 2.
Pretty easy to enter, make your costume, take several pics, get them to the company before October 21st. The best entries get featured on the site, and the winner will receive an original sketch of their design by Dean Trippe.
Sounds cool to me, and gives me an idea or two for something here at Major Spoilers.
More info can be found at the Project: Rooftop site.
