It's a little M&M flow sorter! They even kind of look like cells. If you really want your mind to be blown, go read about flow cytometers: http://en.wikipedia.org/wiki/Flow_cytometry#Fluorescence-act...

Fluorescence-activated cell sorting uses the same idea as in the M&M sorter linked here, except with lasers instead of an iPhone camera and uses an electron gun to deposit charge onto a droplet containing exactly one cell as it falls through a magnetic field to sort it into bins. Madness!
