For a long time, I've wanted to actually make use of the modern hardware I have at home.

For example [https://www.shadertoy.com] has great so-called "shaders" that show off what can be done with them.
Because I also want to toy around with programming some shaders, I want to get a live environment running. So during the weekend, I took the Glew library, wrote a small Perl script to convert the header files to XS, and then fought with OpenGL until I had a driver that could run shaders from Shadertoy.com:
