clsurf

Thanks to Mr. Erik Smistad's excellent minimalist introduction to OpenCL, I have managed to set up AMD's OpenCL implementation on my development computer.

Soon after, I had clsurf up and running. It required some massage in order to work with a recent OpenCL version:

#define CL_USE_DEPRECATED_OPENCL_1_1_APIS

But it eventually compiled and ran successfully using CPU device (I don't have a dedicated GPU on my dev computer) to produce this lovely image:

Not bad for a midnight hack!
