/* Author: Josh Holtrop

|
* DornerWorks screensaver
|
|
* This was a for-fun project I started working on in November '07
|
|
* because I like 3D graphics. I modeled the DornerWorks logo in
|
|
* blender, exported it to an Alias WaveFront object and material
|
|
* file, wrote an Alias Wavefront object loader, and then wrapped
|
|
* some OpenGL and ODE logic around it for various screensaver modes
