The approach sounds interesting, but I think I need help understanding it.

Am I correct that since in this animation all the cones in the "basic set" 
are identical except for the alignment, choosing a specific one of them is 
pointless except for illustration purposes?

In the real hair macro, the point of selecting from a set of basic hairs is 
that hairs pointing in different direction are affected differently by 
gravity. If you had no gravity, you could have just one hair in the basic 
set and use that one for all the hairs. Is that correct?

What I don't understand is why the set of basic hairs is based on a sphere 
covering all possible directions, and not just a half circle covering 
directions ranging from straight up to straight down. When covering an 
object with hairs, selecting from this half circle of sample hairs should be 
sufficient, and rotation would take care of the rest.

This doesn't take into account difference in length of hairs, but if your 
full sphere approach can be made to support that, then the half circle 
approach can too...

It's very possible I've misunderstood something. I'd be interested in an 
elaboration of your technique. :)
