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.
