Johnson circle

The applet below illustrates a configuration of three equal circles concurrent in a point. The discovery of the configuration that has many engaging properties is often credited to R. A. Johnson, although a century earlier the problem in a different guise has been solved by Mary Fairfax Somerville (1780--1872).
