Jeroen Domburg's friend was having a 25th birthday party at which jello shooters were to be served. Jeroen decided to liven these up by creating a 3D printer that inserted a needle into each shot and injected an ink made from banana liquor, food colouring and corn starch in 3D patterns like cubes and spirals. Even cooler: the main body of the electronics in the printer were harvested from superannuated DVD and CD drives, and the firmware for the printer is free software (TGZ) for your pleasure.

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.
