Thank you for providing it to the public! It runs perfectly on my linux 
box (GeForce Go 7600, Ubuntu 8.10, Ruby 1.8.7, ruby-opengl 0.60.0). I 
always toyed with the idea of writing a small GLSL shader development 
IDE in Ruby, maybe this will get me started after all ;-)

One question though:

You know there is File.read, right?
