>It turned out that the rate of ring rotation changed the shape of the pattern from a circle to just about anything, including ovals, triangles, squares and various polygons.

Wow. Imagine if it were a square on Saturn. I think that would provide more fodder for sci fi writers than the hexagon.

The website has an awkwardly placed link. The link mentions "Saturn's South Pole … with its rotating vortex" with a link to another post from the website with a picture of the vortex, but the description is that of "the north pole of Saturn… [a] vortex of strange and complex swirling clouds" encompassed in a hexagon. Do we have pictures of the south pole?

Found one by clicking "rotating vortex" > "infrared images" > "rotating vortex": http://apod.nasa.gov/apod/ap061113.html . I guess someone got lazy.

I can posit a theory:

A hexagon is a boundary shape with the least energy. What you are really probably seeing is a circle that has pushed outwards against another set of forces and reached equilibrium (differing temperatures, gasses, who knows what). I have been playing with voronoi diagrams and diffusion limited aggregation recently , and it is amazing some of the structures that will emerge when a system reaches equilibrium. It is possible that certain forces have aligned with their peak energies in the form of a regular polyhedra, which happens all over nature on large and small scales.

The video attached to the link, "huge vortex rotating" on that Saturn page is... not exactly what I expected.
