The so-called Horseshoe crab came to mind after I wondered what my son would pick.
He described these as a poster child for not evolving.
As I considered how that might sound, I remembered a sketch of a riff that had been sitting on my desktop for a few months.
So I opened the Live document, shifted the loops around a little to sit with the video from Archive.org and then put that exported version through Motion's comic effect.
A riff that didn't want to evolve as a soundtrack to a Horseshoe crab.
