3D

If 3D movies are here to stay and 3D glasses are still required, it's time for Ray Ban or Foster Grant or somebody -- anybody -- to step in and make moviegoers look less foolish. Or perhaps equally foolish but more stylish.

3D glasses in designer frames. A shot in the arm for self-conscious movie fans. An amazing invention for people who can't bear the idea of wearing glasses somebody else just wore. Arguable environmental benefit. Pretty much a Million Dollar Idea.
