This camera called Lytro, invented by a Silicon Valley startup, lets you focus and re-focus your pictures on a computer after you take them, creating multiple focal points.

Basically, photos are adjusted by clicking on the area to be brought into focus.

This is possible because Lytro's image sensor captures more data than any standard camera, including which direction the light came from.

Walt Mossberg WSJ's columnist shows in the video above the process.

The Lytro can be bought at lytro.com, starting at $399.

Users get a free online account to create galleries, share links with friends and post photos to Facebook, Twitter and Lytro's public page, which is like a version of Flickr.

Now just imagine this technology on a smartphone... Nokia/Windows, Blackberry... anyone listening?
