Well, it ended up looking like I thought it would. Pretty, but ultimately not an improvement. It looked a bit like the magnetic structure bucky ball pieces from a couple months ago.
On a whim, I added a new vector which would cause the particles to swirl around the center of the sphere along a coded equator. I started to see hints of nice turbulence swirls so I kept at it. To help emphasize this effect, I modified the rotational vector to have three peaks so as you travel from the north pole to the south, you would pass through three bands of rotation. I also added a perlin noise vector to make the movements seem even more chaotic. [Below] is the most recent video.
The brighter dots represent the positions of the main particles. In order to make it look a bit cloudier, I started using the midpoints between nearby points. If two points have a distance of less than 100, I draw a fuzzy texture between them whose size and alpha are inversely proportional to the distance. So as the distance between two particles decreases, the fuzzy texture gets larger and brigther. Because of this, the ‘clouds’ can appear and disappear as the main particles drift about. Here is another version where I am using simple gradient ellipses.
