Thanks for posting this, haven't seen it before! Original author of the Zoomquilt here. Also noticeable is the Eames' movie Powers of Ten https://www.youtube.com/watch?v=0fKBhvDjuy0 and a similar movie Cosmic Zoom, https://www.youtube.com/watch?v=VgfwCrKe_Fk.
They are both from 1968 and both based on a childrens book about the relative size of things in the universe, to my knowledge the first implementations of an infinite zoom effect.
