3D Technology: It's everywhere. TVs, video games, and now even the iPhone. Kode80, a developer from Florida, has released the Holotoy app for the iPhone which uses the iPhone's accelerometer and, if you have an iPhone 4, the front facing camera, to show and manipulate three dimensional images according to your angle of perception.

Thirteen interactive programs, including four games, are included with the app including a program to create your own 3D pics, scenes, and galleries with My HoloPics. Sounds like quite a little program for only a dollar; no funny looking glasses required.
