Launch the program to let rain drops fall on the screen to draw a circle and a square. Count the drops to compute Pi.
- ARROW DOWN (slow): Visible drops
- ARROW UP (fast): Invisible drops
- SPACE BAR (stop): Stop the rain
The ratio between the drops in the circle and those in the square (multiplied by 4) provides a good estimate of Pi.
