Played around with particles and gimp today. Nothing really special here.
Woah! How do you make it spin?
Very cool as just an abstract but i can imagine something like that in a real model…
To make it spin just use add a empty then go to fields in the particle tab and turn on vertex and increase the strength.
While that is very cool, this really should be in the Blender Tests forum, not Finished Projects. FYI.
I don’t know why there are few replies only. Nice job. Did you try modeling particles using 8’th material channel 
with displacement map, and you can modify particle shape and flow with bezier.
artsy-fartsy! nice!
