Not particularly relevant but there are some commercial tools
that do this kind of thing, they are usually called program 
visualisers.
The best one I've used was for C++ (called iLooK I think) and it
displayed objects as little icons and showed arrows between
objects to represent messages. It could cope with multi threading
by colourising the arrows and you could stop/start the program
like a debugger, attach breakpoints on particular instances etc.

It won a Jolt award for productivity back around 1996/97.
I think they might have done a Java one too, but I never used it.

I think there is a .NET visualiser somewhere too. And there are
several for SmallTalk and Lisp.

None of which helps the OP in any way :-/
