Occasionally we come across very unique apps for the iPhone and iPad. Trimensional is one of those apps which hit the app store just over a week ago. What it does is allows you to use your iPhone 4, iPod touch (4th gen) or iPad 2 as a simple 3D scanner.
The app works by flashing a sequence of four frames on the screen of the iOS device and at the same time, captures images with the front facing camera. By projecting different images from the screen it allows it to create a simple 3D map of a face or any object as pictured below.
