Firstly, the box doesn't have enough vertices/faces/triangles/Polys (or whatever u wanna call them) for the lighting to work.
IanM's Matrix1 plugin set has an improved
make object plain command which allows you to set the number of columns and rows used to create the plain.
Secondly, You need to hide light 0 (The default scene light), or edit its settings so it's not so overpowering.
Here is my fixed code, altho you need to walk the camera backwards to see the effect.
