I love pendantic notes! Steiner chains, Thurston's notion of circle packing and circle packing as an optimization problem are quite different from a theoretical point of view. However, they all have one thing in common, and that is that the end result is an arrangement of circles that you may or may not be able to turn into a lamp :)
