It's the iBallz shock absorbing frame. Technically it's not a case, but it is designed to protect your tablet or iPad from falls. The demo caught my eye becausehad put a Kindle Fire in a rotating drum. I got to watch it be dropped again and again. The image was mildly amusing (and effective, too).
The video is after the break, and so are some photos showing the Kindle Fire fall.
If these images bother you, think of a tablet you don't like and picture it being pummeled.
