Thankyou at GareBear I hope you are inspired to try a version of your own. My first ever was the first screen shot a long time ago, I was just fooling around with drawing concentric circles off-setting them consistently and next thing I knew I had those petal like things Or find an actual crop circle that you find interesting and try and duplicate it. Sometimes you get a happy accident.
