People interested in this will probably enjoy NetLogo and NetLogo3D. It's pretty much the Logo you know and love, but you can have many more than one "turtle" which then allows you to program complex things such as flocking algorithms. Here's an example of it in action: https://www.youtube.com/watch?v=NdpTVAx6AU0 https://www.youtube.com/watch?v=NdpTVAx6AU0 You can even move the box around to see things from any arbitrary direction and distance. It's mentioned in the document, but it doesn't get into what makes NetLogo as interesting as it is. Also, I love this story: "A story Paul Goldenberg recounts from the early days of Logo is that one day a child typed the command love and got the response love has no meaning. The child tearfully reported this to Paul. The next day that error message was changed to I don’t know how to love"
