A Japanese media artist Jitsuro Mase brings 3D to the iPhone. His invention, i3DG, is a device that lets you watch movies in 3 dimensions without the need of glasses.

Both production and playback of the video don’t require special technology or equipment, which means that you can watch any movie in 3D.

i3DG is a playful analog extension to an iPhone or an iPodTouch, converting its 2D display into a layered 3D view. Using the old technique of placing a half-silvered mirror at a 45-degree angle in front of an image, in a new context, the project extends upon 3D displays and iPhones. As a peripheral gadget, i3DG can support a wide range of different applications, from  3D videos and animations to accelerometer-based games.

There is no speculation when this will be out or how much would it cost.
