Nested Circles Patterns with Various Fills
Can also alter the Alpha.
Up to version 3, as I kept adding on extra fills and features.
To get no border line set the line width to zero. I like that effect (like in the 2nd attached png).
I compressed it so it lost a bit of quality but the original rendering is really nice.
Enjoy.
Wondered if anyone knew how to do Radial Gradient Fill of Ellipses ?
(Perhaps Circular might be able to help ?)
