Nothing. An earlier version is on Does MandelVroom use the recursive perimeter algorithm that RMand (a relatively recent PD prog) uses? RMand is quite quick, but doesn't have all the bells and whistles that I would like to see. Briefly, rmand calculate the colors for the pixels forming the perimeter (the entire perimeter) of the screen and if the same, does a flood fill. This tends to flood the 'black' areas (those actually in the set) quickly, where most other algorithms spend most of their time. Anyone working on a full featured Mandelbrot program should consider this algorithm. I haven't implemented it, but understand it pretty well and will be happy to correspond via e-mail with interested parties.
