Anyone heard of Real-D?
They make projectors that shoot out images at something like 120 frames per second onto a special silver coating. Gives the real impression of 3D. They achieve this cool effect by polarizing each subsequent frame and the user wears special polarizing glasses that filter out each image. No more funky red/green colored glasses or flickering glasses that cause headaches.
Adapt this to real world LCD desktops and I think we have another revolution on our hands.
