How to implement a gravitational-like algorithm?

Question

For fun, I would like to implement something that takes an arbitrary string as input and returns a random image that is sown from the string. It should not be super durable or anything else. I would like to do something similar to unicorn / pony gravitators that were once upon a time.

If Gravatar was open source and had an architecture plugin for implementing new types of images, I would like to build one. But I could not find it.

I would like to use Python or Java if possible.

You can look at the code that Qaru himself uses for unicorns: http://unicornify.appspot.com/
