I grabbed Square Wheels and Other Easy-to-Build, Hands-on Science Activities: An Exploratorium Science Snackbook
by Don Rathjen, Paul Doherty, and the Exploratorium Teacher Institute. Here's page 23's fifth sentence:
"By the time the two plates are separated, the fingers of air have formed intricate branching structures in the paint."
The text refers to fractal patterns formed when paint is pressed between two clear plastic plates and then suffers the separation of the plates. The book goes on to discuss self-similarity and computer graphics (listing Star Trek: The Wrath of Khan
as an example).
