Radiolab is my life at work. But while perusing my library at home, I found this episode which I had forgotten all about. Familiarize yourself with Zöe Keating if you haven't already. Her mind is fantastic.
It's 36 minutes that will simultaneously soothe and boggle your brain juices.
I made a graphic for it because 1) I can't resist and 2) I really do hate those sad conjoined default eighth notes in iTunes.
