The Neo3do tablet is designed for people who like 3-D but hate the glasses. It plays 3-D video and converts standard video into 3-D that you can see without the goofy spectacles.

The 3-D effect is sometimes excellent; other times, far less so.

The most impressive demonstration I saw used a clip from the 3-D Blu-ray version of the movie “Predator.” It also worked very well with games like Angry Birds Rio and Fruit Ninja.

Using Google Earth, you can also zoom into a city and then move the image with your finger, making it look as if you’re flying a helicopter over a downtown.

Streaming videos from the Web were less predictable. While some videos looked quite good, others (even some produced for 3-D) had little depth and a ghostly edge floating around some images. You also have to be holding the tablet in just the right place to get the most out of the effect.
