if you create two spheres

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

sphere
	{
	<0,0,2>, 1
	rotate whatever
	}

then whatever the vector whatever is, the two spheres will always be
touching exactly. Obvoiusly it gets a bit harder when you try to put
more spheres.

Obviously this is just a partial solution and I don't really know what
I'm talking about. Oh well
