There is hidden beauty in maths, awaiting to be discovered. It is never too late to explore the worlds of formulae, not as an academic but as a normal admirer. There are several computer apps that can guide you through this journey, check google ;)

"PUG" is the name of a dog breed, with flat & wrinkled faces and short snouts. When I finished the original fractal (the on eat the bottom of the post) I named it "pug" because... it reminded me of a pug! Thus, this variation of it is named "Maurer's pug," since it is a pug transformed by Maurer's curves.
