Adobe's Lens (light field lens)

This is a really crazy thing to understand, it took me a little bit to figure out how it works. The coolest thing about this lens is that it would allow you to 'refocus' an image after it has been taken. Yes, an image that was completely out of focus can be focused exactly where you want it in post-production!!!

Check out a cool video here.

I found a discussion on dpreview about it here.

There is a lot of info with photos at Popular Science's site here.

I will update this post after more digging!
