The most common visualisations of the Mandelbrot set have the set itself coloured black, and the regions outside coloured. The colouring scheme usually reflect how quickly the points outside the set diverge.
But what would happen if we applied similar logic to colouring the inside of the set, and left the outside black?
The following images show the results. They provide an interesting insight into the dynamics of the set. It's a perspective you don't often see.
Xaos by setting the in-colouring and out-colouring options.
I personally love the liquid metal look of some of the images!
