Images of the unit circle under variously truncated #Jungreis function (#Laurent series for inverse #Boettcher conformal map between complement of unit disc and complement of #Mandelbrot set).

The most accurate curve is truncated to 500 terms, but is still very far from the boundary of the set, especially around cusps. The series is very slow to converge.
