Hmm... neat, but I can't seem to make it work...
Ok, I have here an object:

sphere {
 0,1
 scale <5,1,5>
}

I also have three points on a plane (lets call them
p1,p2,p3).  I'd like to have this flattened sphere
oriented on the plane...  Maybe I'm just braindead
tonight, but the reorient macro didn't do it for
me...

Thanks in advance...
