If I have a bunch of random 3-d vectors, is there a way I can find a new
vector that is as close as possible to being perpendicular to as many as
possible of the vectors?

...or practically the same question formulated differently: If I have a
bunch of random points, how can I find the normal of the plane that is as
close as possible to as many as possible of the points? (The average
distance from a point to the plane should be as small as possible.)
