Thanks, I really should have seen that.  The problem now is passing the
correct values for position to the recursive calls.  The thing about LOGO
is that it remembers the position and direction of the turtle at all times,
it will continue moving on a set vector unless you tell it otherwise.  POV,
on the other hand, has to be told where to go and what to do once it gets
there.

Thanks for the input, Paul.
