This post has been making rounds recently. It's in French, but if you scroll down you'll see a video by a guy from Adobe (speaking English) showing off a prototype compound (as in, insect compound versus human simple) lens which allows one to do some pretty amazing stuff:
Selectively change the focal plane
Move the camera viewpoint by a few degrees
All from a single image capture. It's probably several years before the big hardware manufacturers start to take notice, and he says that the compute time to render that image was of the order of a week.
If you could throw a couple of thousand machines at it though...
