Galactic - How to

When creating this galaxy, the first thing I had to do was set the emitters to follow twirling nulls. After I had duplicated and tweaked all the particle settings, I found this animation on accident. It's something the simulation does automatically when setting up this effect and I thought it may be useful for anyone attempting to recreate this effect.... Plus it's freakin badass ^^

Enjoy.
