You can also create automata with video by treating it as a three dimensional world. I did a bit of messing around with this a few months ago[1] and created some examples. The only one I can still find that is interesting is probably this one: http://gfycat.com/SelfreliantUnequaledAmericanindianhorse (Forgive the source material.)
Of course it's hard to look at all of a video at once, so you only see slices of the actual world...
