I have a program that modifies itself as it goes- at the moment, it
merely changes light values to "keep track" of its environment. However,
a (hopefully!) soon to be bot will make random guesses as to what it
should do and keep track of them, scoring them as it goes. Hopefully this
will progress to a genuine genetic-algorithm based bot. We'll see. Of
course, it probably still won't push it own buttons, but we can dream :)
