Apollonius, Descartes, Ford, and Farey


A while ago I posted briefly on Ford Circles. I wanted to point out an interesting short post on the Wolfram Blog by Ed Pegg Jr. that shows how to draw these in Mathematica.

If you can, you should also check out the article by Dana Mackenzie on Apollonian gasket circle packing. Both Pegg and Mackenzie connect these packings to Descartes circle theorem.
