This is one of those *very* cool and *very* addictive effects that come along once in a while. Now, I suspect the Twirls effect isn't new, but it was new to me, so I feel just fine in sharing it with you! The tutorial I found is very nice in that it has a video and a step-by-step text write-up, so whichever mode you like is there! Because the results can't really be anticipated, the most important aspect is "trial and error" to see what you like, and because there are so few steps it invites you to do just that!
UPDATE 2: I have been busily "twirling my brains out" and learning so much. Instead of posting the new ideas here I have started a new thread: Taking twirls to the next level If you come up with an image you like, I hope you will share it here or in the other thread. I so much want to see what you come up with!
Sepiana, I also found the Difference blend mode to produce some fine hues. The symmetry of your image is interesting; how did you achieve that?
Tom, the symmetry (along with the black background) resulted from changing the blending mode to Difference. Then, I ran the file through Topaz Adjust (HDR effect). This made the design pop up and added more detail to the edges.

Thanks for the tutorial, I can see this becoming very addictive. I liked the examples I saw where a recognisable face had been retained, so I tried to do the same by blending in a layer with much less distortion. Not sure it works totally (needs a bit more blending), but will experiment some more.
Tom, What a fun Challenge!!!! The post you shared has some awesome creations.
Here are two twirl actions shared by Diana Day and Steve Rich, two of our EV friends with their permission. Diana recommends cropping your image to a square before beginning. Since Tom added the actions by a direct link I removed my dropbox link.
Using Steve's Action: Duplicated and used multiply blend mode.
It belatedly occurred to me to make more detailed notes how I got there, but although I had not yet closed the History Panel, I am unable to back-engineer it. I can get something similar, but not the same and not as well balanced. I believe the difference lies mostly in the rotations. It must have been just a fluke. Rita
