Graphics

I'm now going through the graphics tutorial on the same website.  I've been following through it, but it isn't actually creating an application, so I just tried to fool around with the ideas they used and actually but them into an application...That isn't working very well.  I still can't really do much on my own, but as I try more things I begin to understand it more and why things don't work.  Its a lot more complicated than working with PHP.  PHP just display things on a page and didn't work with memory and connecting things and compiling and windows and all that.
