Evolution of Julia sets as their parameter point moves away from the center of the largest (or period 2) bulb of the Mandelbrot set, leaves it at a rational point (here with rotation angle 2/5 turn), and crosses into the bulb attached there. The position of the parameter point is shown in red in the Mandelbrot inset at the bottom left. It moves away from the center while keeping the same multiplier angle of the 2-cycle.
