Someone mentioned to me a while back about some guy developing a camera that could refocus images after the exposure had been made, using “Some gizmo containing loads of lenses”, or words to that effect.

Well, here’s Ren Ng’s Standford website about just such a development, a Lightfield Camera.

The maths is heavy, but the basic principle is fairly understandable and the videos on the website are illuustrative. Don’t expect this stuff to be creeping into compact cameras anytime in the next few years, but it’s certainly a very interesting development.
