https://peertube.wtf/videos/watch/075eb29c-6720-4f41-8d18-4b9b5ca5307d This is a talk I gave for the Society for Undergraduate Math Students at the University of Rochester in the spring of 2021. In 2018 I was invited to a conference on universal algebra and lattice theory in Hawai'i. I designed an earring for the conference which depicts an object in lattice theory called the free distributive lattice on three generators. In this talk I show some of the linear algebra and coding involved in writing a Python script which uses the Sage computer algebra system to create an stl file suitable for printing the earring on a 3d printer. Please note: This talk is not about the topological space called a Hawai'ian earring.
