Just for fun: Olympus Bioscapes 2012

It's time again to see the winners of the Bioscapes Competition sponsored by Olympus America. Prizes are given for the most beautiful and/or extraordinary microscopic images, which can be either still or videos. The winning entries must "depict subjects that are, or at one time were, living". You can peruse the winners' gallery here. 

Below is the grand prize winner, an absolutely mesmerizing video of rotifers, taken by Australian Ralph Grimm.
