## Monte Carlo and Buffon's Needles

This applet demonstrates a Monte Carlo algorithm, Button's needles.
Needles of length 1 are dropped randomly onto a sheet of paper
ruled with parallel lines 1 unit apart. The ratio of the number of
needles that cross a line to the total number of needles approaches
2/*pi*, from which we can compute the value of *pi*.

## To run the demo:

- Press the
**Run**button to animate the algorithm. - Press the
**Pause**button to pause the algorithm. - Press the
**Reset**button to clear.
