Boy, are people who spent all sorts of money on a 3D TV that requires glasses going to feel foolish before too long. With advances like Samsung's 55-inch glasses-free 3D TV, those glasses are going to become very expensive paperweights.

Samsung's huge 55-inch prototype allows for nine different viewpoints for glasses-free 3D viewing, and can swap quickly between 3D and 2D modes. Looks pretty slick!

But don't worry, glasses-required 3D TV owners; this thing is at least three years away from market, so you're still the cool kid in town. For now.
