Speaking of fairly innovative things, the Lytro — launched in full today after a tease a few months back that got people excited — just turned the idea of a camera totally on its head. Those long, rectangular things? That’s the camera. No need to put it up to your eye, because, being a light-field camera, it can focus the shot after the fact. And the price point? A fairly cheap $399. That’s what we call radical reinvention, friends. Is this company the Kodak of the 21st century, or something else? We’re totally curious.
