Hahaha this is a fair comment. I guess my intention was to show the complex number crunching that happens in the background to make characters move. I'm still thinking about better ways to visualize things.

Could you overlay the graphs with a sort of arrow, indicating the the actual direction the quaternion is pointing in? I had no knowledge on animation before, this was a great primer! Maybe having the graphs sync up could be a toggle - I feel like at low animation speeds, this would help visualize what's going on.

Got it! I think you should also read up on dual quaternions for more mind-blowing math if you haven’t done so yet!
