A while back I wrote a post on doing rotations with three shears: https://cohost.org/tomforsyth/post/891823-rotation-with-three

This was an inspiration for a talk by Andrew Taylor: https://github.andrewt.net/shears/

...which Matt Parker saw, and now he's made a video: https://www.youtube.com/watch?v=1LCEiVDHJmc
