Sphere and particles

While learning openGL I try to recreate stunning visualisations I found here, on Vimeo. Now, it's time for flight404. Flight404 videos are awesome! Technically impressive and just beautiful. In this video I've tried to add physics to the particles, which are textured quads, that face the center of a sphere. I've used perlin noise for the motion, added some trails and random forces. I've had some help from Robert, but I'm not sure how he implements his gravitational/magnetism physics. I tried to use Newtons law of gravitation but this didn't gave me the results I wanted. When Roberts video is all magnetism based I definitely want to find out how he did it ;-). Especially if the particles rotate based on attraction. Im using standard Euler based particles and stiff springs to keep the particles on the sphere.
