Yeah I’ve always wanted to understand clifford and geometric algebra better. Seems really cool!
I was put off by the apparent difficulty in making it efficient on computers, but according to this you can do it in such a way that this is not much of an issue.

The interesting thing about this presentation is that it claims that quaternions look weird due to them being presented from a confusing perspective - like trying to explain the motion of planets around the earth using epicycles. 🤷♂️
