The Orb A short explanation: "The Orb" is a remote controlled ball, invented in 1987. The ball moves by changing the centre of mass, by moving a pendulum inside the shell. By tilting the pendulum to either side, the ball can turn. Click here to see an animation of how it works (mpg, 3.5 mb). ©Copyright 2009, Per Samuelsson, phone +46 (0)501-70985, email: orb@picsart.net
