Well, I took it as a wobbling surface, not necessarily a plane, which 
could be simulated by placing many objects (spheres or boxes, maybe) 
close together, or else built as an isosurface.  In either case, I think 
the Lohmueller site might be useful (either for the surface or for 
placing the other objects)...but, at the very least, it's got some 
really nice pictures.  ;)  And you can always learn stuff there.
