The Dishmaker is an experimental prototype dish-printer: feed it food-grade acrylic discs, tell it what shape you'd like your dishes to be, and it will custom stamp dishes to spec. The plastic has "memory" and will snap back to its original shape on application of gentle heat -- up to 100 times. A flat stack of 16 dishes dishes takes up as much space as one bowl (though the printer itself is presently the size of a dishwasher). One downside is that replacing a dish while it's still dirty will b0rk the machine.

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.
