Things moving around on the micro level are simply mesmerizing.
To see for yourself, just check out the videos (below) that were recently named the year's best in Nikon's annual Small World in Motion Photomicrography Competition. The winning videos offer a very up-close look at happenings that seem mundane on the surface -- from the development of a fish's inner ear to crystals forming -- but are anything but mundane under a microscope.
The competition showcases some of the best micro-videography from around the world, and this year more than 130 entries were vying for top honors. The entries were judged by Dr. Paul Maddox, assistant professor of biology at the University of North Carolina, Chapel Hill.
Check out the top three winning videos below -- and nine honorable mentions.
