using http://tinyurl.com/cf9u2lt for reference, I made this project. It places dots randomly on the screen and uses their position to calculate pi. Thanks to rhettallain for the idea, you can see his/her version of the project here http://scratch.mit.edu/projects/rhettallain/925746. the dots per second in turbo mode is over 7000, so I suggest you try it out.
