An interesting mathematically based image, I created this Apollonian Gasket with UltraFractal. It is available on Shutterstock and Dreamstime. I’m not sure how I feel about using the watermarked image versus no watermark at all but this is the way it is for now.
In mathematics, an Apollonian gasket or Apollonian net is a fractal generated starting from a triple of circles, each tangent to the other two, and successively filling in more circles, each tangent to another three. It is named after GreekmathematicianApollonius of Perga.
