Anyway, today as I was surfing, I came across a truly unique site - one with which I could waste any number of hours, should I so choose.
Musical Pi, or pi10K, allows you to assign notes to numbers between the value of 0 and 9. Once you've completed this simple assignment, it will then "play" the song of pi as you've written it, out to the first 10,000 digits. Wow.
Give it a go. And make sure to check out some of the other experiments on avoision.com - my favorite is Round.
