Thanks! It worked out. I had not used a #while before, so I learned two
things. It really shortened my scene file. I had a whole bunch of
object {
    Myobject
    translate ...
    rotate ..
}
...

I didn't understand the formula, but after experimenting with different
things (Height), I was able to get something going. Thanks.
