It sounds like you've got the beginnings of Machine Learning (classification & regression), but I'd still recommend checking out Coursera. The JHU Data Science series is good, but more geared towards DS than AI. There are others on there as well; if you're looking to get into deep learning, I echo the recommendation to check out Ng's course, though this might be good, too: https://www.coursera.org/course/neuralnets

Nice! Very cool that it can include Lizard & Spock as well.

Looks like there's code in different languages, so the arbitrary 500 line count gets even more hazy. As an extreme case, consider 500 lines of APL vs. Java.
