Researchers at the Berkeley Institute of Design (BID) have developed an interesting stereo display. This link gives a short description of the devices and has links to more detailed descriptions. The page suggests that the display should be driven by camera input, but you could also replace each camera input with the output from a video card that is showing something that has been rendered using OpenGL. If 1 or 2 groups want to try to use this device for their project, they should contact Dave Nguyen
