Software Image Focusing

This paper explores an interesting technique for measuring the angles of light rays at each point on a CCD, by using arrays of small lenses. There's a decrease in the resolution of the image, but the data captured can be recomputed to generate photographs focused at varying depths in software. This also means that photographs can be taken with larger depth of field without changing the aperture. I'd really love to have a camera that could do that...
