OpenGL and FreeBSD

I have always wanted to do everything cross platform but when you dont know what youre doing and dont have much time it tends to be the last thing on your mind. So a few weeks ago I wrote a simple windows application (using OpenGL) to easily display points in 3D space instead of having to draw it on paper (doing vector maths at university at the moment). I also happen to have just set up a computer with FreeBSD (and GNOME).
