IPython (http://ipython.scipy.org/) enables parallel computations to be performed interactively. In this screeencast, we show how IPython can be used to study a large number of digits of
pi in parallel. In particular, we calculate the frequency of all 2 digit sequences in the first 150 million digits of pi on a small cluster running Windows HPC Server 2008. IPython enables this parallel calculation to be performed in a fully interactive manner.
