The electrical charges from a VDG generator can stream off a point, but gather around a sphere.  While connected to the VDG's sphere and seeing the hair-raising effect, you can alternately point and make a fist and usually can see the difference in your hair.  When you point, the hair should go down a bit as you are allowing the charges to stream away from your body.  The hair should go back up when you make a fist.  Sometime you can even hear a squeaking sound when you point your finger.  (Quick, get out the VDG!)
