Stand-up Maths

The Big Feastival is this weekend! https://thebigfeastival.com/ (Or if you are watching this in the future: some weekend in your subsequent August.) I'm there most years, come and say hi! In 2023 we're making a giant sun dial. Blur are on tour again and have a new album out! I've seen the show and listened to the album so can recommend both personally. https://www.blur.co.uk/ https://music.youtube.com/playlist?list=OLAK5uy_kx0OirV41v6j1vuMqU_1dpeK-qZv1RXOg Huge thanks to Robert for finding all eight "Eight Kite-Rhombus Solids". https://robertlovespi.net/2018/04/29/eight-kite-rhombus-solids-plus-five-all-kite-polyhedra-the-convex-hulls-of-the-thirteen-archimedean-catalan-compounds/ Thanks to Lisa Mather who designed and laser-cut all of the kites and rhombi so we could cable tie them together. https://twitter.com/lisa_mather Internal frame for the balls was designed and built by Dave Ansell. https://www.sciansell.co.uk/node/167 3D design and all images of the shape was done by Sam Hartburn. https://samhartburn.co.uk/sh/ The build crew included but was not limited to: Alex Genn-Bash, Alex James, Ben Sparks, Katie Steckles, Lisa Mather, Lucie Green, Matt Parker, Matthew Scroggs, Paul Taylor and random festival attendees.
