just for fun: Nikon's small world photomicrography competition

I was perusing on the good ol' internet when I stumbled upon this really neat competition that Nikon has every year.

Quick introduction (taken from the website http://www.nikonsmallworld.com/):

"Small World is regarded as the leading forum for showcasing the beauty and complexity of life as seen through the light microscope. For over 30 years, Nikon has rewarded the world's best photomicrographers who make critically important scientific contributions to life sciences, bio-research and materials science."

There are some really cool pictures. 

The winning picture (shown below) for 2011 was from Anna Franz.
