Turning a Cell Phone into a Microscope

The Pacific Northwest National Laboratory (PNNL) has developed a low-cost, 3D-printed lens for a smart-phone that can magnify objects 100x, 350x or even 1000x, allowing students, first-responders and others insight into our little world.  They even provide downloaded files for free (I love free) so you can have your very own printed.
