The ground is warping which seems to be a common over-scaling issue, but it looks very very good otherwise.

True, I fiddled with it without getting much better results (in some cases the effect works well, like using is for waves).
Now that there are so much comments, I regret not having spent more time to make it perfect! I think it could have been easy to split the giant cube into small planes to avoid overscaling and get the same effect. Maybe next model!
