The creepy fingers that grow from a vibrating cornstarch-water mix can be modeled as a chain of inverted vertical pendulums (DOI:10.1039/c4sm00265b) and are believed to be the fingers of Maxwell’s Demon trying to push through into our universe.

I used to have a simulation of a double pendulum as my screensaver, and it was so hypnotic that when I was out of the office, no one in the office could work either. I had to change it.

My bad, I chose the first example video I could find that was less than five minutes long. I previewed it, but without audio since I was at work.
