Quote - I thought of using a magnet, but I'm still learning about them, so my efforts weren't very good.

A couple of tips for using magnets. The Mag Zone determines the area affected by the Mag, with the Mag's influence falling off towards the edge of the zone. So if you wanted the whole head to scale evenly you would make the zone very large. Another point to conceder is that when you scale a Mag the scaling happens from the center of the Mag Base outwards. So moving the Base down will tend to raise the head, and moving the Base up will move the head down.

There is a good tutorial on using magnets at PhilC's site.
