Bumpy Baskets and Geodesics

I participated in the SCULPT Show&Tell earlier this month, with a talk connecting the topic of bumpy baskets to geodesics and, rather slightly, to the interesting topic of closed photon orbits. Thanks to Negar Kalantar and the other organizers for the event and making it available as a YouTube recording. Much cool stuff was presented, my own talk starts at 52 minutes in.
