sorry, what I am trying to do is have an image to start with, then for repetitions of that image to fan out in a circle in a clockwise motion. Then, when that circle is complete, I want the ‘fan’ to ‘close’ in a clockwise motion also. So the repetitions begin to disappear from the original start point. Hope that makes more sense. A way to describe it would be to say that it looks like it’s chasing itself.
