The device attaches to your iPhone and helps you capture, view and share 3D video clips. The device works by lenses that combine two video streams into one 3D video. The designers are currently looking for funding for the work on Kickstarter. Here is more about the project:
When you look in the viewfinder, Poppy’s lenses combine the two video streams into a single, crisp, 3D video. It’s beautiful, and really hard to describe or show in two dimensions. It doesn’t need batteries and there are no electronics. It’s just optics and your iPhone’s camera and screen, so we can keep the price low without sacrificing quality.
