I've always loved this sort of cloth animation. I think the first one I saw was dissimulate's tearable cloth demo on Codepen - I can't believe they wrote that code 9 years ago!
That was me! The original version I put on codepen was about 13 years ago. I can’t believe it either… until I realise that was before I landed my first programming job, and it feels like ages.
