A friend of mine worked the stage design and setup for Prince's superbowl hafltime show. Apparently he is a FREAK - you're not allowed to look at him or talk to him for any reason, even if you're designing his stage show, and all visual efffects must work to make him appear taller, yet you cannot mention that fact openly. For instance, lights come up from the floor making him cast a big shadow etc. He does rock a mean guitar though.
