C++ Turtle Graphics

I'm sure most of you probably have a basic idea of what turtle graphics is. I need a version of turtle graphics using actual graphics instead of the traditional ascii characters. This could be openGL, SDL, DirectX, whatever. Just graphics, even some type of console graphics would be great. I have the base code for the program that does ascii characters, so it shouldnt be too hard to make it graphical. More detailed instructions and the base code(which is actually C code, but compiled in my Visual Studio 2008) are in the attached file. This project is urgent and must be completed within 12 hours. The simpler the better.
