Doing Advanced Particle Motion Properly

This project demonstrates proper OpenGL 3.2 custom shader support combined with the OpenCL/OpenGL "interop" functionality. Though there are few comments, the code has been designed to be relatively easy to use and understand, and largely portable. Aside from a few platform-specific issues (chiefly among them being the hardcoded $PLATFORM variable in run.sh) the code should work on most platforms.

Perhaps the only "gotcha" is the auto-generated source file src/Shaders.java. Perhaps impulsively, the code ends up constructing it in a shell script that then compiles it into a Java class. The reason for this was simplicity: the entire project can be contained in several JARs and a collection of native libraries. Compilation on non-POSIX platforms might get tricky, however...

In terms of licensing, all files in lib/ and ext/ are covered under the LWJGL license in doc/LWJGL_License.txt. All files included in src/, and classes/ are under the following license. Naturally, if another license is preferable, then naturally I am open to suggestions.
