documentary 'nebulas'

i have been working on a documentary with BYU: there is a scene where we enter the creative genius of the subject of the documentary... basically the shot was described as a blobby nebula where energy travels into it and then out. not a lot to work with, but i like a good challenge... this one wasn't quite the direction that they were looking for. if you ask me, it was too cool. the following are tests that i have been working on lately... we went from 'blobby nebulas' to 'mixing colors of cake batter in a swirl' - this is what i came up with [the spins are a little fast, but they're tests]
