We'd love to insert a joke about eating pie here, but then that doesn't really do justice to the awesomeness of this little useful application. Homebrew coder Art has created Pi Calc version 1, an application that calculates Pi for users, up to 30,000 digits of Pi to be exact.

As Art explains in his readme, there are a couple of reasons for wanting to know the value of Pi:

One is a benchmark, or speed test when running the same program across different platforms. Another is to generate seemingly random numbers, or seeds for algorithms that produce pseudo random numbers. Another reason is just for fun!
