Day 162. I just came across this online programming tool called PencilCode. It's really very cool (if you're into that kind of thing). It allows you to play with code and explore programming. It's pretty easy to use, although, unlike something like Scratch, it does involve actually typing the commands so it requires you to learn the correct syntax in order to get things to work. It's a bit Python-like. But mostly it's impressive because it runs in the browser and so is perfect for student use. It would make a great follow up language to Scratch for keen students.
Anyway, this is just a simple program I created in my first dabble with it. Nothing too fancy, but definitely worth exploring further. You can run it here http://betchaboy.pencilcode.net/home/Circles (and remix it into something else yourself)
