I've been working on a *very* cheap system.  I just finished a board (4 x 7 in)
that will generate modest wireframe stereo images at 256 x 192 pixels.
Update rate is 30 Hz. for each eye.  Total cost was about $75, not including
a DSP chip I borrowed.  Assembled the thing in my spare time, in my 
basement, using mostly scrounged parts.

Yes, the resolution is real low, but most TV LCDs are only a little better
(300 x 200 ?), I think.  And yes, it's not sexy Gouraud-shaded polygons in
16.7 million colors, but this is something you could slip into a coat
pocket.  Beats carrying two Personal IRISes on your back :-)

Don't have a tracking system yet, but RS-232 is on the board, so I could
plug into a Polhemus, I think.  Anybody want to lend me one?
