Try This:
SuperPiByHand -> Get a stopwatch, and a pen and paper. Start the stopwatch, and then get to work. Stop when you get 1M digits of pi.... mmmm... pi. Then stop the watch, report your time. Way more impressive than having a pc do it and about as obscure as your method.
Seriously though. While its nice to include multicore support, SuperPi is pretty much the gold standard of the Pi calcs.
