Green flag. Space to reset local variables. Down arrow to add local variables to cloud, allowing you to estimate pi on multiple machines, getting closer to pi every time. TURBO MODE!!!! If you like it, love, favorite, or even follow me! Thumbnail by @RichardStarbright
http://en.wikipedia.org/wiki/Buffon's_needle A 12px (needle) is dropped onto a grid of lines that are spaced at 11px intervals. The needle will appear randomly on the screen, pointing in a random direction. Each time it is dropped, it changes the dropped variable by one. If, when it is dropped, it is touching one of the black lines, the crossed variable goes up by one. Then, it performs the operation (d/(c/2)) where d and c are dropped and crossed, respectively. The answer is an estimation of pi.
