Thanks. I took the sampling code from here: cs.caltech.edu/~keenan/project_qjulia.html
The stuff I did was mainly the way the quaternions are controlled, and the raytraced shadow. If you are working with xna I could send you an example project, but otherwise I recommend you look under the "ports" section, and grab the shader code most suitable for your favorite hlsl/glsl program, and build the set-up yourself; it is not very hard, and you'll learn a lot.
