If Star Trek gave us cell phones, Star Wars will give us holographic projections to go with them.

Researchers at Hewlett-Packard Labs in Palo Alto, CA are working on developing a 3D holographic display that can be viewed without glasses, from several angles, that could be used in cell phone technology.

I may need to get me one of them.
