ahem. more formally: provide animated uniforms to the shader, and use them
the tutorial just wants us to do three matrices, and to defer all the actual math to a library it recommends. that would certainly be simpler. anyway, we use quaterion+offset for everything but the projection frustum, and do all the math ourselves

kinda cool how the driver interfaces with the kernel to map memory on our behalf

in the words of the tutorial, "We are already getting quite close to seeing something pop up on the screen"..... it took THREE DAYS. encouragement is great and all, but perhaps don't trivialize that effort
