In order to run our project, simply make the project and run "lrt 
seashell.rib".  The following list is what we did to get the final 
image in the project.

-thin film interference
-thickness map for thin film interference
-NURBS surfaces for modeling seashell
-Phong normal interpolation
-bump mapping (for all of the shell)
-perlin noise (for the book page)
