This is a Sunday morning experiment to capture and control a still photo like the Lytro [ http://www.lytro.com/ ] camera. This is a quick 2 hour project using my old Nikon D-SLR and coffee. The result is below, do give it a minute or two to load as it is a 1.5 mb file. Once loaded click on the photo at different points to have it focus at the desired depth.
