In the same direction that 4-D spacetime curves... :-) Seriously, those 3-D (2-space + 1-time) scientists would simply say that the direction of the spin-vector is a mathematical contrivance that makes the math work. Just because no 3-D entity could point his finger in that direction doesn't make the concept useless. -- franl@centerline.com || Fran Litterio, CenterLine Software R&D 617-498-3255 || 10 Fawcett St, Cambridge, MA, USA 02138-1110 "It's not the thing you fling, it's the fling itself." -- Chris Stevens
