Unusual and beautiful solutions to the Three-Body Problem.
He has seven pages with multiple examples on each page. Take a few minutes -- they just get wilder as you go.
(Three planets chasing each other around a figure-eight orbit can be stable. Who knew?)
Way cool. Thanks Doug.

Very nice! I've declared it "Physics Day" in my department and sent around the link.

The old cliches about the ship "spiraling out of orbit" don't seem quite so awful, after all.

Celestial mechanics is the new crack. (You should see what I got in the lab.)

So we might yet discover planetary rosettes?

Rosette-like behavior, probably. Stable rosettes, unlikely. Note how sensitive Butikov's configurations are to initial conditions.
