11082019 this design used both polar coordinate filters in Photoshop

Another couple of versions of an abstract because I am not sure which I prefer, this original one or the other with a yellow background. This one started from a very long narrow vertical section of this previous abstract www.ipernity.com/doc/philsutters/48563368 . The second version is the identically same image, but with the 'hue' slider in Photoshop Elements moved a long way to the left and the colour saturation increased.
