You can literally store bits of information in a zoom path by, for example, zooming in on a spike of a seahorse julia set and choosing to go either left (0) or right (1). The information is then encoded in every shape you get to see from there on.

Never noticed that. Really cool.

Seems efficient.   

  We can send messages with Mandelbrot set coordinates.  This will end up in a movie in three....

You can do the same thing with babushkas by going left or right. Someone should
tell Dan Brown...

The principle is called "steganography". You obscure secret information by hiding it within a larger amount of public information. The secret bits then seem to be an innocent part of the whole.

The novel "Cryptonomicon", for example, uses a shuffled deck of cards to store the secret key of a symmetrical cipher.
