Piano peace! In 360 and with 3D audio (you can look around and move the view!). Check out the making of video, it's REAL COOL: https://youtu.be/x1zJoU6Luss Use your phone and youtube app with headphones to be able to look around with spatial audio on this video. The making of video also includes a flat version so you can see it all at once. This is a collaboration with mathematician Henry Segerman, with additional help from physicist Sabetta Matsumoto. There’s a surprising amount of theory behind this video that we get into a little bit in the making of. Crowdfunded on Patreon!

Best Shape 2018! This video is VR180, so if you have a cardboard or other headset you can see the shapes in stereo, or look around in magic window on a phone or drag the video with the cursor. Scutoids are officially named for the first time in this paper: "Scutoids are a geometrical solution to three-dimensional packing of epithelia" https://www.nature.com/articles/s41467-018-05376-1 Special thanks to Clara Grima for answering my scutoid questions, and to Laura Taalman and Tom Ruen who contributed to the creation of paper scutoid nets based off of 3D scutoid models by Laura Taalman, who invented the packable pair of identical scutoids (see https://www.thingiverse.com/thing:3024272 ) , and John Peplinski, who created the space-filling cairo tile scutoid design (see https://www.thingiverse.com/thing:3042446 ).
