It took me the long weekend (on and off, I did other things too!) to redo the 7 lessons (now 6) using FloatArray, VertexArray and my new VectorN and MatrixN and ColorN classes which are also subclasses of FloatArray.

I think it was a worthwhile rewrite. The objects lend themselves to the way OpenGL actually operates well. As a result, I decided to redo the GPU math test to see what numbers I could get now that things are easier to work with. The results are staggering. I could get a consistent 2000% to 3000% improvement using C to do the floating point math, but the GPU wins on bigger data sets easily:
