When I first saw this picture, I thought that this guy had gotten frustrated with some kind of weird do-it-yourself exercise equipment and was about to toss it into the woods. I was at least right about the DIY part.
This strange contraption is a DIY plenoptic camera. Still don't know what that is? I didn't either. Make explains that "instead of capturing a flat, 2D array of pixels, a plenoptic camera uses an array of microlenses to capture 4D lightfield data. This data can then be processed to create a final image that is focused on any part of the scene." If you want to get dreamy about describing this gadget, you could say that it lets you travel back in time and fix bad focusing mistakes of the past.
It looks crazy in action, too:
You can follow the link to Futurepicture and actually read all about how to make one of these camera rigs yourself. And if you do, please send along some images. I have this fascination with these trippy, crazy things. [Futurepicture via Team Droid via Make
