If you’ve been following along #awegif2021 on twitter, you’ve seem me post a few animated gifs that look like the image above (days 1-6 specifically). These are known as Chladni figures, named after Ernst Chladni. He described the formulas that create the patterns that result when you use soundwaves to activate sand or powder on a flat surface. You can find a ton of videos on Youtube that feature real world examples of this. But it’s also fun to do in code.
