The team was amused by the Lytro camera (the one that lets you adjust the focus of pictures after you take them), but the price tag was a bit steep for their tinkering budget.
So they built a hack that lets you create the same kind of images with a basic digital camera!
They took the functionality of the $400 Lytro camera and made it so that anyone with the internet and an SLR can make pictures with an interactive focal point all on their own.
