I'm putting together a project to be used as a fun intro to programming -- getting some hands-on coding experience is the real goal, but it is presented as a game.
Started because I was asked to lead an activity on programming for the young men at church. One week down, two more weeks to have it ready. It's a big project (hoping for it to have more life beyond this specific activity), and I'm also learning a lot in the process, it's been a lot of fun so far.
