I made a song parody about quaternions this afternoon: https://www.youtube.com/watch?v=MD8HNlgpFJg

I was inspired by the talk Casey gave 6 years ago where he talked about Ken Shoemake's paper, and mentioned that he'd find a quaternion musical funny.

Well, it's not a musical. But I enjoyed making it. And I thought I should try to throw it Casey's way somehow (and twitter is imploding right now, so I thought to use forums).

Thanks for listening if you did. Have a nice day!
