This project is a very basic introduction to Greenfoot.
A microphone is required for this app to work properly.
The application will start with a balloon centered in the screen. Once running the balloon will begin to drop as gravity is applied to it. If it hits the bottom it will bounce and lose a little momentum.
The application uses the computer's microphone to monitor sound levels. If sound is detected, a small amount of anti-gravity is applied proportional to how loud the sound is. Once sound stops, gravity slowly takes over.
If a balloon hits the top of the screen it will pop.
You can add new balloons by clicking on the screen.
