I'm trying to crate an animated background for the game I'm doing that looks like a spiraling galaxy. Sort of like this:
Or like this photo (but in motion):

I can use the orbiter behavior to create rotating star fields, and they look good. But I was trying to create the CLOUDS that appear to be endlessly spiraling into the center of the image (into the sun or black hole or whatever) and I'm having no luck.
Is there a trick to animating an endless loop like that? Should I be trying to animate this as a sprite and paste it into the background? (That'd be a BIG sprite, the game runs at 1920 x 1200).
Any suggestions appreciated! Thanks!
