Nice to see old Lytro hardware brought back to life.
When they were launching the company, I was so excited about the possibilities. Maybe naively, I was really rooting for being able to take a photo, and then in their software (and later in Lightroom) be able to slide/brush-in/out points of focus. Alas, all we got were these gimmicky square pictures that you could click to bring various parts to focus.
