A DirectX 8 Tutorial!

This is a spinning 3D cube made using DirectX. It contains the following features: -Zoom In/Out -Change Textures -Rotate 2 ways -Turn on/off 3 different lights -Enumerate hardware, display modes and device -Change textures at runtime I spent a good bit of time commenting it. Any votes are appreciated but what I really want is some feedback telling me what you think. If it goes well, I may upload and make more stuff like this.
