Actually, I've been playing with that, too, but the image is not so 
great because I'm a crappy modeller. This technique is based of Jaime's 
macros. I've been directly calculation the location of each spline out 
of stubbornness. Jaime relies on the trace function, which means you can 
filter the triangles with an object. I think his method using trace is 
superior to mine. I had to reinvent some wheels to get to a point of 
understanding, though.

In the attached image the sky and clouds and "grass" are all fairly 
normal (the "grass" is a plane at y=0), but the attempt at a starry 
water scene is actually sitting at y=-20.
