    This needs to be more generic. Currently it only supports rotations around the origin. It should allow any arbitrary point as the center of rotation.

    helped me get my head around it nicely - check out tibees on youtube (Imaginary Numbers Explained Bob Ross Style) if you want to follow the same train of thought - and then try to work out what coordinates give a 60 degree angle 0.5x +(root3)/2 i

    What about when you need to rotate it from the point instead of the origin?
