Shoot First, Focus Later with the Lytro (UPDATED)

This is one of the most revolutionary cameras of our time. With a new camera, a bunch of lenses focus on your subject first, then it snaps the photo. The Lytro lets you focus the photo after you take the picture. It does this by recording the "light field". Essentially, it not only records the light hitting the sensor, like a typical digital camera, but it also records the direction of the light ray. In doing so, they've created a camera that uses more software than physical parts, and allows you to take one photo, and produce multiple photos with different levels of focus later.
You can check out examples here. Below, I have more info, as well as an example of a photo changing focus after the photo was taken.
