Amazing Ferrofluid Animation

On Twitter, I follow the amazing Maria Popova, who also curates the very cool Brain Pickings website.

(That yellow and white together are wonderful.) This morning, Maria posted a Twitter link to the following animation featuring ferrofluids, a substance I first encountered at the Exploratorium, and then later at another exhibit in the New York Hall of Science.
