Happy Leap Friday! For your enjoyment, some ferromagnetic fluids jiving to a piano piece:

One of physics’ greatest tricks is polarization. Take magnets, for example, such as those commonly found on refrigerators holding up shopping lists and Christmas cards. These have the familiar north/south polarization that we can experience as attraction and repulsion.
"I see miracles all around me
Stop and look, it's all astounding
Water, fire, air and dirt
Fucking magnets, how do they work?
And I don't wanna talk to no scientist,
Y'all motherfuckers lyin', and gettin' me pissed." -Insane Clown Posse
I'm an experimentalists through and through, and have always known better than to attempt real theory. On two occasions, though, I've been forced to do a little bit of computer simulation work in order to interpret my results.
These are great: ferrofluids are stable suspensions of ferromagnetic particles.
This is why I told you at SQuInT that if I didn't do quantum info I would switch to experimental fluid dynamics.
