Check out the following video. Salt is poured on a vibrating table. At certain frequencies the salt gathers into interesting patterns. Someone should take some of the shots and Photoshop them. Would make some good art.
God is the author of math, physics, art, and beauty. It should not surprise us to see the beauty within each of these disciplines. Further, it is amazing when those fields overlap.
If you search Youtube for cymatics you come up with some other interesting films. Cornstarch and water is another good medium.
“God, you amaze me.”

Reminds me of my structural
Reminds me of my structural dynamics degree, it’s about time I got to use that! What you see is the salt highlighting the nodes of the structure. The nodes are the places on the structure that don’t move while adjacent spots are vibrating. So the salt dances around until it finds a spot that isn’t vibrating. Higher frequencies means more nodes means more salt outlines.
Practical application: This is a graphical way to show how a designer concerned with isolating something (say the floor of a building or the seat in your car) from a specific frequency (say from an earthquake or your car’s dynamics at 70mph) could attach to the structure at some specific locations to minimize movement during the dynamic event.
Humans are pretty smart and can describe almost anything with F=m*a, but I wonder if we’ll ever figure out “why” F=m*a is what it is rather than F=m*a*pi.
