3D Orbit Visualization

I made this tool to teach myself a little about Javascript and WebGL. Turned out to be quite a neat little project that I'd like to share. You need a WebGL enabled browser to run it. The graphics work on Firefox but the range inputs do not, so I suggest Chrome. You can rotate and and zoom the left window with a drag/scroll of the mouse. Let me know what you think.
