Decided to play with the twirl filter in Photoshop again. Took a picture of a smal stained glass window and came up with the following abstract.
The last one is my favorite. But I did learn from Enrico Sottocorna, from his blog post here, that the Affinity app can also produce this type of abstract. He has spent most of the quarantine time learning his way around the app. I looked at the site and learned that the app has a 90 day free trial. Therefor, I downloaded it and will try learning some of its tricks.
