I created a game app based on the “Buffon’s Needle” experiment from my previous post. What makes it interesting is the seemingly mysterious fact that you can approximate π simply by dropping needles onto parallel lines—without drawing a circle anywhere!
This could also make a fun app-development exercise for junior high and high school students. So, let’s take a look at the app I created. For this kind of project, I usually use MIT App Inventor. In this case, the ImageSprite feature was especially useful, allowing me to implement the needle-dropping action quite nicely.
