Tiny, Lens-Free Camera Could Hide in Clothes, Glasses

This is the biggest invention in this era.A tiny, paper-thin camera that has no lens could turn conventional photography on its head, according to new research.
The device, a square that measures just 0.04 inches by 0.05 inches (1 by 1.2 millimeters), has the potential to switch its "aperture" among wide angle, fish eye and zoom instantaneously. And because the device is so thin, just a few microns thick, it could be embedded anywhere. (For comparison, the average width of a human hair is about 100 microns.) this is very good invention it would also help us to our security purposes.
