They're not that magical. Multiplication with complex numbers is a neat way to do 2D rotation and scaling. It's the same idea with multiple dimensions.

  An idea which is encapsulated much better by geometric algebra, in which quaternions and complex numbers follow the same rules.

      I think it would be self-damaging not to.
