-2 points: The cell shading didn't always work correctly, becoming staticky at times.
-5 points: The vertex shader from Problem 2 did not actually move any vertices.

-5 points: The vertex shader from Problem 1 did not actually move any vertices.
-2 points: Lighting on the shark didn't change when the light was moved around.


ID #441 (18/20)
---------------------------------------------
-2 points: Interesting (but incorrect) colors on the cell-shading.


ID #515 (10/20)
---------------------------------------------
-2 points: The vertex shader from Problem 1 moves vertices in eye-space, not object space.
           This means the vertices always move towards and away from your eye, so you can 
           never see the movement.
-3 points: The fragment shader from Problem 1 just produced noise, as it didn't correctly
           compute the L vector.
-5 points: The vertex shader from Problem 2 did not actually move any vertices.
