It does look fun. I haven’t used it, but I’ve briefly used Python’s version of Logo called turtle.py. It’s just a Python library though, so doesn’t have all the little buttons and other nice features. It’s still fun to play with though.
I forgot all about NetLogo until you posted on this again. It definitely looks like something I would like to play with. I think one of my main interests in programming is in using it to experiment – with math, art, etc. Agent-based modeling seems like another fun thing to experiment with.
I’m planning to work through this course soon. I think his book, The Model Thinker, is the textbook. The print version will be released in March but the Kindle version is already available. I figured I could read it while watching the videos. I’m going to finish his Complex Adaptive Systems book first though.
(Edit: It doesn’t mention it on Coursera description, but another website said that the examples in the course are in NetLogo.)
