Quaternions are left handed spinors. Please use the correct unified math models (clidfford algebra) rather than these 3d only hacks.

Describing those algebras in quaternion terms simplifies understanding most of them. Like biquaternions and dual quaternions.

A 2d quaternion just has no j or k term and works for 2d math.
