I thought that was the case, but the tutorial I was looking at 
didn't have any shaders at that point. I added a shader program.

Aha! Yes, that's it, thanks! Once I understood the difference 
between VAO and VBOs, it was easy to fix. Thanks!

Thanks very much for the resource! I had already looked at about 
a dozen different OGL3.x tutorials online, but this was the one 
which clicked for me. I'll definitely look into getting his book.

Thanks again!
