I've seen these as well, and the 3D effect isn't too bad... Even having only two layers can give your brain a lot more depth information.
My biggest problem with these displays is that they do a horrible job of occluding the back layer. Any object in the front layer that is supposed to be opaque, but isn't black, becomes translucent. So, if you're trying to display a red car driving in front of a building, you can see right through the body panels of the car. It's really rather distracting...
In the giving credit where it's due department, MIT has been running similar programs since 1990. It was a big deal back then, since they caught a quarter of the class. See the article from The Tech, MIT's newspaper.
