Meet the Lytro.

Make it magic.
Lytro lets you take pictures like never before. Unlike a conventional camera that captures a single plane of light, the Lytro camera captures the entire light field, which is all the light traveling in every direction in every point in space.

Capture everything - instantly.
Capture living pictures with the press of a single button. By instantly capturing complete light field data, the Lytro gives you capabilities you've never had in a regular camera.

Focus after the fact.
Since you'll capture the color, intensity, and direction of all the light, you can experience the first major light field capability - focusing after the fact. Focus and re-focus, anywhere in the picture. You can refocus your pictures at anytime, after the fact.

And focusing after the fact, means no auto-focus motor. No auto-focus motor means no shutter delay. So, capture the moment you meant to capture not the one a shutter-delayed camera captured for you.
