Sand Box Thingy

It's a box that has zen garden type vibe to it, the box has a plane that flows like sand being pushed up into it. The blue box on the top is glass but for some reason its not showning up like that in the preview. If you download it and using blender, set render engine to Cycles, exeripmental mode and it should work. I don't know how to use other 3D modeling software well enough to know if this works in others.
