Cracked.

Think i have it cracked now.
I like this one for the final hand-in.

Also enjoying the little moment it stops at the edge. It's not completely realistic, but i like it.

3D-ness...yeh.

Had a quick play with maya today.
Went all out with the light and shadows, though will give this amiss when its not a test :)

This one was with just keyframes, no tweaking frames, and was all done with the splines in the Graph Editor.
