Hi, for all fluid mechanics buffs out there:
Here's a picture of some 2D vortices shed by a flow across a cylinder. The zig-zag patterns are actually non-detailed version of Von Karmen Vortices. The 2D condition is made possible by producing flow along a soap film, with gravity as the body force driving the flow. Enjoy!
