Well, if you want, I've got a macro that uses the hyperbolic functions to do
the drop, which I used for the rope in my IRTC image from the SEA
competition.  It calculates the appropriate points given a 'lowest' point on
the hyperbola, and returns a vector of them.  There is another macro out
there for doing this, but IIRC, it uses a parabola, which isn't realistic in
some cases, though a good approximation.
