Strange attractors in R

Pete Werner has posted some very nice images on his blog, Shifting Sands, that use R’s nuts-and-bolts image() function to draw thousands of tiny dots, one for each position a particle is at as it zooms around some kind of chaotic attractor. I have only glanced over this post quickly, said “whoa, cool” and it’s getting late so I can’t claim to understand exactly what he’s done, but I’m interested in the image more than the chaos. I think it’s nice because it’s simple, and almost transparent (not in the technical RGB sense). Who needs colour?

He then has some weird stuff going on in a video that involves him throwing his hands in the air like he just don’t care, while the computer does something with the resulting data. Worth a look, as long as you turn off the music first!
