The people of EyeSee360 are showing their new invention called GoPano Micro. This unique accessory is a lens that is placed over the rear iPhone camera and becomes your phone into a 360° video cam recorder, all controlled by software that you can manipulate using the tip of your fingers.
The GoPano micro records all around 360 degree at the same time, and then you can playback your video allowing you to see any angle.
Unfortunately it is not yet available on the market, but if you want you can make a pre-order for $50 in Kickstarter (already with $94,000 from an initial goal of $20,000, not bad!). Here is a video showing how this lens works.
