Nice, Roger! Of course, one could apply this to dynamic
presentation languages such as SVG or X3D as well. Someone
with time should try the BOIDs simulation.
Of greater interest over time would be non-linear conditions
in production environments that have queues and contention
for resources. One would want an interface that let the
player change conditions, for example increasing certain
resources in response to the queue conditions and using
feedback to the queue to enable it to reorganize spontaneously.
Then one is approaching the kinds of dynamical systems
the web exhibits in response to feedback that generates
links, eg, blogging behaviors and their effects on
directing innovation and their inhibition of it.
Thanks for taking the time to build this proof of the

I have implemented the Game of Life using XSLT.
It's kinda neat! It nicely demonstrates some aspects of complex systems
such as evolution, attractors and feedback.
For example, here is a simple starting configuration (a filled-in square
means it's a live cell, an empty square means it's a dead cell):
After applying the rules of Life once, the configuration evolves to
Then, after applying the rules of Life to that output (i.e., feedback),
the configuration evolves to this:
Below I chronicle the configuration's evolution. It settles into a
repeating pattern when it gets to the sixth iteration (the pattern
alternates between configuration 5 and 6 indefinitely). These two
states represents an "attractor".
Each configuration is represented as an XML document. Here is the
