Yesterday marked the official launch of Lytro - a new start-up company that is actually promising some serious innovation and actual technology. They've developed a camera that captures images using a light-field (aka Plenoptic) which captures more data about an image than what is currently available. The big push on this is that you'll be able to dynamically change the focus point on any image way after they're taken. Their photo gallery has a ton of examples of this in action - giving you the ability to shift focus from foreground to background and back again. Obviously this is great from a speed point of view (no need to focus anymore) and will allow the photo to sort of "live" after the fact.

As a concept it's an incredibly impressive bit of work. From a practical standpoint I worry that the first run of cameras will be ridiculously expensive and that the viewing mechanism for the images will be subpar (i.e. what if you have to run them all through lytro.com and some sort of poorly done embed? boo). But only time will tell what they've got in store and based on the buzz about it, I'd say we'll all hear about it right away.
