Camera technology is always being used/tweaked in one way or another to yield surprising or novel results. In some cases, that means creating a camera that sees like a bug's eye. In others, one that perceives only motion, like a retina.
The most recent camera innovation we've stumble across falls a bit closer to the second of those. It's called Pixy, and it's a color-detecting camera that might some day soon be the eye with which your friendly neighborhood robot sees and interprets the world.
