This Experimental, Single Pixel Digital Camera Takes Color Pictures

A single pixel color digital camera sounds an awful lot like a camera that captures a single bright red, green or blue dot, but when scientist Ben Greer set out to build his own single pixel camera, that's not what he was creating at all.

No, by moving a little autmatic arm in front of the sensor, scanning the scene multiple times, and then getting into a bit of math, he built something that can take actual pictures.
