How can I learn about video game graphic design?

I am a sophomore at The Ohio State University, whose major is Computer Science and Information, and I was wondering if I could get any information on becoming a game designer. Since I was young, I have always wanted to make video games, but I didn't know where to even start. I would consider myself a good artist but I was hoping that I could improve on it this summer. If you could give me some information on summer classes and seminars for game and graphic design I would greatly appreciate it.
