ShapeShifterZ makes printed workout gear that makes you look like a totally buff superhero (or stone gargoyle, or voodoo doll, or whatever). It's machine-washable, wicking, breathable, and marketed as suitable for workout gear, Burning Man, or what-have-you. They come as two-piece or one-piece suits; apparently the one-piece suits are better for hiding rolls and the like but you can wear the leggings as yoga-pants.
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.
