The idea for this project came from one of the recent crop circles (alien or not). The challenge is to create 12 circles touching inside two concentric circles. Hint: If the radius of the inner circle is r1, and the radius of the outer circle is r2, then the radius of each of the intermediate circles is (r1+r2)/2. The challenge is to find the coordinates for the centers of these intermediate circles to be able to draw them.
