Since I only actually want to do this in 2D, it occurs to me that one  
trick would be to have a large sphere sitting only partly embedded in  
the plane and have it move "up" and "down" to cause the circle in the  
plane to grow and shrink. If the other circles in the plane were  
shallow cylinders the collisions ought to work out appropriately.

Still, a less hacky solution to the general problem would be good.
