This is a collaboration between legendary minimalist composer Philip Glass and rainy day childhood staple Sesame Street. It is called Geometry of Circles. Somehow, I never shared this before. I am so sorry.

Years ago, a friend linked this video and I nearly wept with the recognition of something I knew so clearly from childhood and never since. This is perfect. Literally. I can’t imagine a more direct pairing of music and visuals; form and content reflect and amplify into the very essence of an idea.

Behold the hypnotic logic.
