Not from me, but very cool:
Browse through the thread and probably you will find the most beautiful renderings of the mandelbrot fractal you've ever seen!
Those deep zooms are nice for testing arbitrary-precision integer mulitply performance and since this guy has provided the coordinates and coloring algorithm, I am already working on some kind of benchmark for CPU (GPU and parallella support also planned).
Will the Parallella be fast at this kind of computations?
