Fascinating!

If you doubt the intuitive and way-beyond-human-perception genius of J. S. Bach, the video below can sure change that. Mark Frauenfelder, at BoingBoing, said it is a :

video of Canon 1 à 2 from J. S. Bach's Musical Offering (1747) being turned into a Moebius strip, then played in two directions at the same time.

If you don't understand a Moebius strip or Bach, don't worry, enjoy and know you are seeing something amazing. Bach was beyond understanding at the very depth of his musical soul.
