Simple iteration circles with curveVertex.

About this creative coding artwork.

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! 🙂
