Triple Directional Monitor from Sharp
Sharp have added to their list of great goodies a 3 way directional LCD monitor. Simply put, you can see three different images from 3 different angles.
From straight-on, to the left an to the right you can have 3 different images displayed, allowing the driver to see a map, the passenger to see pictures of their destination and the person in the back to watch a movie.
It does seem like you will need quite a video card to pump out 3 different images at the same time, unless there is some more elegent solution to getting the 3 images.
Sharp already have a dual directional monitor on the market.
