A Po

-I have found the scrolling circle of the ipod before it came out. This was a solution for an alarm clock, instead of using buttons to set up the time, I thought of the digital circle.
-A car cabin that would slide between two rails. For security purposes during a crash, the cabin would be slowed down by front and back springs.
-I have thought of the camera for the cell phone before it came out
-I have thought of the cell phone`s screen switching to a mirror before it came out
