[Pault]

At one point in time, our floor pickup could pick up upside down disks. Since then its been changed and somewhere along the lines it started rejecting them. However, once they are in, we have no problems jamming (because we don't stack frisbees, we store them in a line) and can shoot them exactly the same way as normal frisbees. We also mechanically have the ability to differentiate between right side up and upside down, but we never put it to use in code. All of this is possible because of a flange sticking out of the middle of our frisbee path which forces regular disks to be flat on the floor and upside down ones to be pushed up against the ceiling.
