A little off the beaten track for me, but this reminded me of many wasted hours waiting for my Amiga to render a Mandelbrot image. This is an example of a 3D render of a Mandelbrot series being hosted via skytopia. The “Unravelling of the 3D Mandelbulb” has many more examples. Goodness knows how long this would take on my Amiga?!
