Tryckcykeln: 4 Color Printing by 4 Colored Bicycles
People will have to get very creative when the lights go out; Swedish design students Calle Enström and Johan Undén certainly did when they turned four bikes into a colour printing system. After all, they say "Vi gillar att cykla och vi gillar att trycka". (We like to cycle and we like to press.) There is one bike each for cyan, mangenta, yellow and black. They printed a book on it as well.
