On: What I learned as a hired consultant to autodidact...

[Animats]

I've encountered people with a cult interest in quaternions. To anyone who does 3D graphics, they're just a convenience. But they can be visualized as a point on the surface of a 4D hypersphere, and there are generalizations to higher dimensions and to representations where you can express "rotate 720 degrees". For some, that way lies madness.

When you find a quaternion cultist, turn them onto octonions.

Blasphemer :-) Affine transforms

TIL there is an affine cult.
