Enormous thank you to Desmos for allowing us to make the animations in this video. Desmos is an incredibly powerful online graphing calculator available at https://desmos.com/calculator. Desmos usually only works in 2D, though, so to make 3D projects like those in this video, you'll have to implement it yourself.
