# The creative coding artwork with simple iteration circles

It's a creative coding still image artwork made with Processing. It draws simple iteration circles with curveVertex.

Simple code and beautiful results! It draws a various pattern of curves. It's so fun to wait for the next drawing result! 🙂

## Processing code example.

Please feel free to use this example code under the terms of the GPL. To see other works based on my code is my pleasure. And my honor.
