Meet Lytro

Oh my. I want one.

Check out this amazing camera. Most cameras only capture 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. Which means instead of a standard photographer capturing one plane, you instantly capture complete light field data.

What does it mean? It means the future is here (and it's not a jetpack). Now you can focus after the fact, essentially since you'll capture the color, intensity, and direction of all the light, you can focus after the fact. Focus and re-focus, anywhere in the picture. Here is an example.
