A simple solar corona project for After Effects 7.0. Fixing the seam is left as an exercise for the reader.

Very cool thingee to look at Stu, but any chance for those of us who f.e. use Fusion, that you might describe what you have done here, so we can try to replicate?
"Polar Coordinates" remaps the y coordinate of the source image to a radial coordinate (distance from a center point) and the X coordinate to an angular coordinate (direction from the center point). So for example a horizontal line would get wrapped around a circumference of a circle and a vertical line would stick out radially from the center of the circle. Vertical noise thus becomes radial noise.
@ anonymous: I do know what Polar Coordinates do, but since I couldn't open the AEP file, I had no idea Stu was using this tool.
Thanks for the help though.
Well, I went ahead and gave it a shot to get rid of the seam. I tried Mirror; it works but of course it looks too symetrical. No good. So I put the fractal noise into a precomp and tried using offset on a dup layer over the original. Nope, still a seam. So on a dupe of the Fractal Noise layer I made a narrow vertical mask of fractal noise with a nice horizontal opacity falloff, Polar'd it and layered it over the seam. That worked pretty well, though it seems kinda overkill. Finally, I tried opening up KeyCorrect and used Wire/Rig Remover over the seam. That actually worked pretty well, too, and was way quicker. Sigh. How would you have done it, Stu?

Shows how much I know, I don't even see a seam
