"Gray Julia" is the Julia Set of a rational function that has a pole of order 3 at the origin. The white regions are 'pre-poles'; that is, a point is colored white if its orbit enters the "trap door" surrounding the pole. A point is colored black if its orbit remains bounded. All points except the black points have an orbit that eventually escapes. The number of iterations,it takes for the orbit to escape determines the color.
