Manimals - an universe created by numbers

I don't know if I heard it or read it somewhere and then forgot about it or if it is genuinly mine, but one sentence has been on my mind often lately. I've been reading about different branches of Artificial Intelligence, and it led me to say: We should not be in business of making intelligent machines or agents, we need to be making universes.

Here's an example of a simulated universe, (temporarily) called Manimals. Looks funny doesn't it? I didn't have seen any traces of intelligence in it... yet! ;-)
