I am looking for code example of pixel and vertex shaders in processing. Anyone had publish a example?

I check and try some of this code, but I have compile problems:

I am trying with code with "CG" class from "AC" user (Reply #9 on: Oct 7th, 2006, 6:41am).Maybe I make something wrong but when I compile the code (I am using OSX and processing0125), and I check "libjogl_cg.jnilib" is inside openGL library folder:
Code:

I guess the error is caused due to creation of CgGL.cgCreateContext() ?
I have the same issue, if you found out the solution do let me know.
Thanks
