What you're seeing in this beautiful short video are particles from a printer toner cartridge floating in water. The strange patterns come from the little flakes responding to magnets.
This film was created by Kim Pimmel, who describes it like this:
Ferrous printer toner particles floating on the surface of water are attracted by a magnet and align to the invisible magnetic field around them. The patterns and motions that result are strangely ordered and organized.
Time-lapse sequences were created from individual photos shot with a Nikon D90, DIY macro lens and custom intervalometer. Edited with Adobe Premiere.
It's part of a series he calls Compressed, "choreographed time-lapse shorts that explore the beauty of the forces of nature that surround us." Can't wait for the next installment.
