That would be awesome, I can see not being able to find my glasses as I'm about to start watching a 3D movie. Dont the glasses provide slightly different images to the left and right eyes? How would they perform that without glasses? Would you have to sit straight behind the TV, thereby limiting viewing angle?

I found some information...

A new line of 3-D televisions by Philips uses the familiar trick of sending slightly different images to the left and right eyes -- mimicking our stereoscopic view of the real world. But where old-fashioned 3-D movies rely on the special glasses to block images meant for the other eye, Philips' WOWvx technology places tiny lenses over each of the millions of red, green and blue sub pixels that make up an LCD or plasma screen. The lenses cause each sub pixel to project light at one of nine angles fanning out in front of the display.

A processor in the TV generates nine slightly different views corresponding to the different angles. From almost any location, a viewer catches a different image in each eye.

Providing so many views is key to the dramatic results. Sharp Electronics makes an LCD display that projects just two views, requiring an audience to sit perfectly still in front of the screen. With the Philips technology, viewers can move around without losing much of the effect -- one set of left/right views slips into another, with just a slight double-vision effect in the transitions.

With the panasonic panel i would not know. But according to this article, with the sharp tv you have to sit directly in front of it. And with the philips television you have a more flexible choice of where you position yourself in front of the screen.

This would probably work better for a computer than a TV-- viewing angle

i saw an awesome 3d TV in japan at some science museum. it did not require glasses, but you had to stand a certain distance away and look at it head on for the image to pop.

You don't need special glasses on the holodeck of the Enterprise.

They've been out for a while actually
Here are the two technologies out for it

Supposedly you can convert any screen to 3D by putting on a parallax barrier or buying lenticular lens for it.
ex: this site sells lenticular lens and software to make you display 3D

I'm currently looking for a set of lenticular lens to convert my 24" LCD.

But impressive nonetheless. My son watched the video & thought it was a hoax.

THese guys have been selling these for years:

Not sure why it isn't more mainstream/well known. When they were reviewed on Anandtech many years ago the reviewer was blown away with it.
