The authors would like to draw the reader’s attention to a YouTube videoFootnote 1 by Benedikt Hahn, Paulina Hering, and Pavel Zwerschke that provides a crash course in hyperbolic geometry and presents a beautifully animated proof of the seven circles theorem, based on our article “A Hyperbolic View of the Seven Circles Theorem,” which appeared recently in this journal.Footnote 2
