This omnidirectional camera which is still under development, takes a 360 degrees photo and it sends it to you smartphone! It seems that this is the next step beyond the SLRs...
It has two fish-eye lenses, each of which covers 180 degrees. The camera combines the two pictures, and sends them via Wi-Fi to a tablet or smartphone for viewing. The idea is, the pictures you take arrive automatically.
When viewing it like a regular panoramic image, you can also see up and down. When you pull out from the image, it finally becomes a circle, and you can also look at it as a sphere.
