Vortices in my coffee and the Perpetual Ocean

In a previous post I shared a video on mixing and unmixing of fluids. This time I share with you an image I took of my coffee. With some milk fluid dynamics created amazing vortices. Following it is an animation of the time evolution of the vortices.

I also share this NASA video of the visualization of the (perpetual) ocean from June 2005 to December 2007 which displays vortices that run the ocean surface currents.
