Ganson 2

Arthur Ganson is this amazing kinetic sculpture artist that you can find out more about from http://www.ted.com/talks/arthur_ganson_makes_moving_sculpture.html or http://www.youtube.com/user/dreamingmachines This sketch uses a turning wheel (move b or press play) to move two constrained rods. Point S moves back and forth betweenthe midpoints of the rods. What do you notice about the motion of S? Is it periodic? In what way? Can you make your own machine sketch? Or add a feature to this one?
