Inspired by this thread in the Show and Tell forum, started by Shawn Kraus. It's a lot of fun going through my pictures and figuring out which ones would look cool flipped inside-out. Most images have a link to their source picture.
I did some Amazing Circles-the polar coordinates, also used a free plugins by Flaming Pear and got some that I liked better. links to flaming pear in the description as well as links to other plugins that make some pretty nice digital art. Usually link are in the 1st of a series of a particular technique.
Love these Amazing Circles and liked that you tried a quite a few images and showed the ones that were not so amazing. Liked seeing the origin. Excellent
