But I am trying to make a head-mounted display.  LCD-shutter glasses are ok,
but when you turn your head 45 degrees to the right, you have no picture.
I plan on using only wire-frame, so real-time rendering is not a problem.
There is also the problem of tracking the head movements, but that might not
be too difficult if we could use the ultrasonics from a powerglove.
