3-D Without Glasses

Someday movie fans may be able to watch 3-D flicks without needing cheap red-and-blue glasses.

A team of University of Arizona scientists has created what may be the first rewritable 3-D display surface. One image can be replaced by another in a matter of only minutes.

The team hopes to get the time needed to rewrite the surface down to only a fraction of a second. Such a development would make it possible to present 3-D films using the technology. If it works, say goodbye to needing 3-D glasses.
