For a presentation I'm doing tomorrow, I made some animations of n-body choreographies (n equal masses which share a common trajectory). I put these up on youtube since that seems to make more sense than having them mangled by Blogger or hosting them myself:
Twenty-one bodies
Eight bodies
Three bodies on a figure eight
The videos are done using Sage, the Tachyon raytracer, and ffmpeg. The orbit data is from Carlos Simo.
Here's a 2D picture of the twenty-body choreography.
