Ryan, I'm not sure what you mean by an "auto-scrolling" background  
image in 3D.  The 3D display doesn't have scroll bars.  It's not the  
same concept.

Java3D has two facilities for background images:
	- An image that you just plop in the background behind everything  
else (warning -- Java3D doesn't do this efficiently)
	- A spherical image that you use to tile the outer boundaries of the  
universe around you -- think of it as the "sky" in the background.

	Mason can do both -- you just need to hook it in the right place in  
Java3D.
