I decided to have a go at animating one of my images from a year or two ago. It turned out pretty well, with the gas swirling around and the stars moving past. Of course none of this represents real distances or motions, it was purely about what looked good. I was pretty happy with how it turned out.
That's a pretty cool effect Markus, 30 seconds longer would be better. Great job though, I like it.
Thanks: i haven't tried to see the longest it can be sustained for, though obviously the effect has limits. Maybe I'll have a play with it and see what can be done.
