It would be like finding the face of Jesus on a piece of toast, or the face of an alien on a satellite image of Martian surface. (Both of which were actual images that gathered some cult following in their time.)

Spend enough time applying human interpretation to non-human processes, and something will eventually come up that tickles your senses.

I think we already found that ;)

"What if one day we found a _____ that contains a message from god?" describes almost any ancient divination method. One of the things that draws us to fractals is that they show us how iteration over simple rules can built complex structures that resemble forms from the natural world.

What I'm saying is, asking this question isn't a whole lot different than cutting open the liver of an animal sacrifice and trying to divine the will of the gods from the interior structure. Or cutting the throat of a prisoner of war and reading the splatter. Or watching the flight of birds. It doesn't say much.

I play around with fractals a lot and once I fiddled with mandelbrot and found something that resembled a pig running on two legs.

I guess it would be called the running pig fractal.

This might be a message from god: don't eat pork.

I suggest you real Carl Sagan's only novel, _Contact_.

It's very good and by modern standards it's quite short.

As you read it you will discover why it's relevant to your question.

The real question is "how would we know?" To some, the very existence of fractal behavior may be the message itself - the message of infinity.

this one's message seems pro-piratical

Generate enough digits of pi and you'll find it.

Also check Library of Babel, there are some there too.
