I've just added a Mandelbrot example to the wiki: http://wiki.tiker.net/PyCuda/Examples/Mandelbrot
It uses a pure GPU solution (ElementwiseKernel) and two CPU numpy solutions, it was based on an older Numeric Mandelbrot example from a couple of years back. Both the GPU and CPU solution use complex numbers, I have it running on WinXP, CUDA 2.3 and pyCUDA 0.94 with Visual Studio 9. Could someone take a look and make sure the GPU solution is a 'good answer' to the problem? I spent yesterday hacking at it, it does what I expect but I'm still very much learning. Possibly instantiating 0+0j complex numbers in the ElementWise kernel is a slow operation? Regardless it scales very nicely, a 2000x2000 plot takes 2.1s with the GPU and 51s with the fast numpy code.
