Stop what you're doing and watch this. It's a video of sand. Sand skittering around on a vibrating plate, to be exact. But what happens when that sand skitters is amazing. Trust us – this is something you want to see.
What you're watching is the Chladni plate experiment, as performed by YouTube science-and-illusion wizard Brusspup (he can also coax water into a zig-zagging stream, and make Rubik's Cubes that aren't Rubik's Cubes).
