Pondering a thingy that would depend on adding/multiplying vectors (as in an angle and magnitude) -- perturbing points in a grid. Has anyone already built abstractions for the basic ops? Would save me some time.

EDIT: Turns out what I'm doing isn't so complicated, so, a library is not really necessary.

Huh -- the visual is actually kinda comprehensible

Eventually I realized that my specific case can be done more easily with Cartesian coordinates, so I'm just keeping them in that space. This cross product is good for future reference
