%N The circle curvature (rounded down) inscribed in the area related to critical point of Mandelbrot set at C = 1/4.
%C Inspired by "The dark side of the Mandelbrot set".
%C Consider the case of C = 1/4, 0 <= x <= 1/2, draw the inscribed circles in the area between parabola curve, y = x^2 + 1/4 and the line y = x. The circle radii are found with the "tantantan" function from AutoCAD program. See details and illustration in the links.
