Simulating Neural Networks with Mathematica

Artificial Life in your Web Browser!
The data x is randomly sample I've made a youtube blog about artificial intelligence before, it's been a long-time interest of mine. In that blog, I believe I mentioned an artificial life simulation program I'd written. It's a simulated 2D world in which little "ants" live. The ants are controlled by randomly connected neural network, and they can choose an action at every time step, such as turning left or right, moving forward, eating food, drinking water, or reproducing.
The ants need both food and water to gain energy and survive. They can choose to spend some of that energy to create a baby (another ant with a mutated version of the parent's brain). The interesting thing is that although the ants are initially very dumb, they eventually evolve to seek food and reproduce on their own. There is nothing forcing them to do either of those things, but only the ants that succeed at it can stay alive. I think this has some interesting philosophical implications about real-world lifeforms. It's also, perhaps, an interesting "proof" that natural selection really works (you can see it happen before your eyes!).
Anyways. I ported the said program in JavaScript, and you can run it in a web browser. If you're interested in trying it, click this link. You can click "fast mode" to let the simulation

In 1994, one of those gurus, Esther Dyson, made a striking prediction: that the ease with which digital content can be copied and disseminated would eventually force businesses to sell the results of creative activity cheaply, or even give it away. Whatever the product — software, books, music, movies — the cost of creation would have to be recouped indirectly: businesses would have to “distribute intellectual property free in order to sell services and relationships.”
For example, she described how some software companies gave their product away but earned fees for...
