I just changed the code to use the File#read and re-posted it.  I feel 
silly for doing it the way I originally did.  I cut-and-paste some code 
from another program and didn't think to look for a better Ruby way. 
Thanks for pointing out the area for improvement.

On another topic, what kind of performance / fps are you getting?  My 
past experience has been that Nvidia has better OpenGL drivers than ATI.
