Watch your Apple iPhone display 3D video with the Palm Top Theater case

At SXSW in Austin, a  new case for the Apple iPhone was displayed. Using a very old optical illusion called Pepper's ghost, the Palm Top Theater case allows videos on the screen to appear in 3D. The trick is in the use of three small drop down displays which actually consist of one full mirror in the rear with two half mirrors in front. The reflection from the Apple iPhone's display goes into the mirrors to produce a 3D effect.

The Palm Top Theater requires a special file format that splits the iPhone's display into three parts for the mirrors and a special app is available so that users can make their own 3D videos. The case is priced at $36, but does limit the viewing space. As a result, this is not something that you are going to want to keep on your Apple iPhone 24/7.
