Yoshihito Isogawa makes fascinating “drawbots.” His robots are built out of LEGO parts and create intricate spiral art. The base of Yashihito’s machine is an inverted Lego base. Underneath the base are magnets mounted on gears from Lego education kits. The artist/tinkerer lays a sheet of paper over the base and allows pen holders – made from LEGO bricks, common ink pens, and what appear to be paper clips securing the pens to the bricks – to move in unison with the spinning magnets below.
