Dave created a quite fab Super Mario 3-style map for the Toronto subway system. Delighted with the popular interest in the design, he's offered it for sale as a poster.
Toronto TTC Subway/RT Map – Super Mario 3 Style (Thanks, Fipi Lele!)
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.
