I love the idea 
and I think you are on track attempting this kind of morph and imbrication of shapes for the challenge. I didn’t have time to work on it as of just now but I am also thinking of working shapes. I am sure you’ll find the correct way to use them for @Cedric 's infinite loop challenge.
Don’t try too hard though; I still hope to find some time to participate and in case, of course, I expect to win the challenge
