Designed by the creative folks from Objetgraphik for the 2008 Saint Etienne International Design Biennial, Paul Hoc is a robot drawing machine that moves like a skater on ice. And although it’s not the best painter in the world, it wanders the paper with shaky precision and gentle moves, to create a set of dizzying patterns that are both intriguining and hypnotizing. It looks like physical computing and art do mix together, and the outcome is pretty cool. [via Objetgraphik]
