Snowball is Pixeljam's Flash take on a computer pinball game, and it's an incredibly fun table. I intended to play for a few minutes to try it out and got sucked in for an hour. Snowball is simultaneously very true to the spirit of physical pinball while managing to deliver a board and several mechanics that would be nearly impossible to create in a mechanical game. The vertical scrolling mechanism is also a nice way of transcending the constraint of the usual landscape aspect ratio in computer displays.
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.
