LightSpace Technologies has created a cool (albeit retro looking) 3D display using a number of liquid crystal shutters. The result is a screen which is actually 3D, with 20 different z-positions!

The DepthCube z1024 3D Display is a rear-projection volumetric display in which a high-speed DLP(TM)
video projector sends a series of 3D image slices into a 3D projection volume. The projection volume is
composed of a physically deep stack of 20 electrically-switchable liquid crystal scattering shutters. At any
instant in time 19 of scattering shutters are transparent and only one is in a white scattering state. We
switch a single shutter into the scattering state and project onto it the appropriate image slice
corresponding to its physical depth. Since each image slice is stopped in the projection volume at the
correct depth, the DepthCube produces a 3D image that is truly deep.

A patented 3D anti-aliasing hardware algorithm virtually eliminates the visual discontinuities between
layers so that the 3D image appears to be completely smooth and continuous.

Why I blog this? It would be damn fun to play with for the graphics course I am currently taking.
