Niklas Roy, a professor at art university in Germany (where else?) recently challenged his students to create functional computing systems using nothing more than cardboard, welding wire, glue, rope, rulers and cutting knifes. To prove it could be done, Roy also created a cardboard computer himself–the ingenious plotting machine in the above video.
Roy’s students submitted some insanely impressive work as well, including a mechanical car racing game, a binary logic machine, an information distribution knot, and an Angry Birds-style minimal shooter. Creative Applications has some mesmerizing GIFs of the apparati in action.
