Neural Networks, wth?

I'm delving into the world of artificial neural networks, one of the main tools to create artificial intelligence. I dunno why, but I'm fascinated by the math behind it, even though it's very hard to understand and all. So far, after like 5 to 6 tutorials on the net, I can only briefly understand how does the neural network works, but I still don't know how am I supposed to use it. Hmm... hopefully, I can learn everything by the end of this week.

Oh, and I have just started planning for the map editor. It won't be easy, but I'll try.
