In this flow visualization, wingtip vortices from an aircraft have been simulated using an apparatus with a couple of flaps that snap together like a book closing. Dye is pooled on the “ground” below the flaps and gets entrained by the vortices and lit up using laser light. The red vortices are the primary vortex generated by the aircraft wingtips and the green ones are secondary vortices generated by interaction with the ground. The lower half of the picture is a reflection off the ground. This photo was part of the 2009 Gallery of Fluid Motion. #

Bubble Art
Bubbles are all about surface tension and minimizing energy. Arrange things just right and you can even make square ones. (via JetForMe)
Tempus II
While not strictly fluid mechanical Philip Heron’s Tempus II features some great slow-motion action of fluids. (Submitted by @ftematt)
Ferrofluid Art
Magnetism and fluid dynamics collide with ferrofluids! Ferrofluids are a suspension of ferrous material in oil or water, but their behavior around magnets can elevate them into a work of art (or a car commercial). Why leave it to professionals, though, when you can make your own ferrofluid?
Liquid Umbrella
Droplet collisions, usually with water or milk, are popular with photographers for their artistic value. As stunning as these still images are, high-speed video makes the effect even better.
