C OpenGL Framework

I have made a C framework to allow me to code some opengl based demos, now I just have to think of something to code as far as effects are concerned. At the moment the only thing I have made with it is a test conversion of a Blitzmax effect based on the juggler from the RSI megademo. My version uses sphere's and sits on a reflective checkboard.

Here's a screenshotSince most of the stuff I have coded before has been oldskool style effects I am looking to move forward alittle and try something newer.
