It’s a new camera technology called the Lytro and it sort of shoots pictures in three dimension so you never have to worry about focusing or missing that perfect moment. Check out this story from the fine folks at NPR and don’t forget to click on the pictures to understand how this works. I can see many possible uses in the surf or boat when all hell breaks loose…LOL
flies, sand & surf 
Awesome. Can’t wait to see it up close some day.
Looked at the Lytro camera on the NPR page and clicked around, Actually laughed out loud, just fantastic.
