On DeviantArt, Genesischant has a great "Jazz Age Justice League" poster complete with back-stories for all the reimagined, Gatsby-era vigilantes. I especially love Wonder Woman as a flapper, and the Green Lantern as a soldier-turned-jazz-musician-turned-crimefighter.
The J.L.A. is a borderline legal bounty-hunter/vigilante group with limited governmental sanction ("Department of Justice Licensed Agency"). Made up of individuals from various walks of life, all are committed to the take-down of the rising criminal empires that threaten America.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
