A camera that couldn't care less about focus: introducing Lytro

``The basic premise of Lytro's technology is pretty simple: The camera captures all the information it possibly can about the field of light in front of it. You then get a digital photo that is adjustable in an almost infinite number of ways. You can focus anywhere in the picture, change the light levels -- and presuming you're using a device with a 3-D ready screen -- even create a picture you can tilt and shift in three dimensions. (I got a demonstration of the camera's 3-D photos on a laptop and was blown away.)''
