Awesome, and thank you. I will look in the ports tree as soon as I'm done writing this reply. I am still interested in seeing your source code for the perl program that generated isolation, or at least hear more about how it worked - primarily because I think it's a neat idea. (I'm already thinking about what data would be represented in the most interesting manners, when presented musically...julia sets? monk locations? hmm...)

Thanks again for the excellent description.
