I just posted this over at Progarchy, but I wanted to include it here at Fractopia. I probably should have waited until next March 14, but what the heck!
I recently discovered this song by Alan Stewart that the good people at Numberphile posted. It’s a prog tune based on the digits of pi and tau. Now, before you turn up your nose at the thought of combining random digits with music, give it a listen. It’s quite good and packed with mathematical puns. For example, the camera makes a complete circle as the tune unfolds.
