Virtual reality entertainment is slowly approaching the mainstream. And it's doing so in what looks like a UFO.
Lytro first burst on the scene in 2012 pushing a small $150 camera that let you refocus pictures after you took them. Advancing that idea a step, Lytro then released the Illum in 2014, a more robust take on the original Lytro with a zoom lens, bigger sensor, and more advanced features. The core of these cameras is something called light field image sensing. To risk oversimplifying a bit, this basically means the image sensor is capturing the color, intensity, and direction of light beams (most camera sensors omit direction), letting it create 3D representations of whatever it's receiving.
