Myron W. Krueger using a computer that interprets human siluettes has put together a virtual reality space where a persons body, unencumbered by annoying attatchments, is a tool for interacting with the program. This seems to be quite a liberating interface design which enables people to freely move about as they interact with the program but without well designed software the experience could quickly get boring. Being able to freely move my right arm and freely move my right leg to get a response from the program would get boring fast if both the moving of my right leg and the moving of my right arm caused the same reaction from the program. Myron meets such challenges though and creates very interesting works. Krueger developed METAPLAY which allows the artist and the participant to have a collaborative drawing experience. It seems as though this form of art owes something to the work of Jackson Pollock which brought the excitement of process to a more central focus in the visual arts.
