Just found this awesome new camera-
This camera by 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. By instantly capturing complete light field data, the Lytro camera gives you capabilities not possible in ordinary cameras, the ability to focus where you desire within a taken photo. Since you’ll capture the color, intensity, and direction of all the light, you can focus and re-focus, anywhere in the picture. And focusing after the fact, means no auto-focus motor. No auto-focus motor means no shutter delay.
The light field is a core concept in imaging science, representing fundamentally more powerful data than in regular photographs. The light field fully defines how a scene appears. It is the amount of light traveling in every direction through every point in space. Conventional cameras cannot record the light field.
The way we communicate visually is evolving rapidly, and people’s expectations are changing. Light field cameras allow the picture taker and the viewer to focus pictures after they’re snapped, shift their perspective of the scene, and even switch seamlessly between 2D and 3D views. Pictures can become immersive, interactive visual stories that were never before possible – they become living pictures.
You can have a go on here
