Logo was my first programming language! I recently rewrote my own version of it so that I could draw a time-proportional train map. I wrote "fd 5" for 5 minutes, for example. http://peterburk.github.io/tra/ http://peterburk.github.io/tra/ The version I wrote can read values from a spreadsheet, so could be used in other applications too. I think this kind of thing could be a great way for a young person to go from a homework project to the front of Hacker News. If any of you have kids, I'd be happy to help gather the data for some other subway networks!
