I read about a 3D display in EETimes that I think had been built by TI.  It
was a plastic hemishpere that enclosed a clear plastic disk or ellipse that
rotated at high speed and was drawn onto with a laser beam or bright light.
The image with this kind of approach is viewable from any angle without
glasses or special optics.  The picture showed a bubble about two feet
across.  It was being demonstrated at some convention like SIGGRAPH.
I don't think TI invented this approach and considering how slow the big
companies are in bringing out really inovative products I would suggest
pursuing it anyway, even if the method is the same (so long as they
haven't patented it.)
