Well, I was supposed to be going through bills today, but no - I HAD to start playing!
I have two variations on this challenge. Not really trying to emulate a traditional art technique, just playing with filters.
For this first one, I used my kaleidoscope action a few times and transformed/layered the different kaleidoscopes. Then, merged all and applied the Dreamy Photo filter. Duplicated the layer and applied a Mosaic filter. Twirled the mosaic layer and changed the blending mode to Lighten.
