Iphone, ipad and android application.
When the phone or tablet hears a sneeze sound green waste (like snot from a nose) is displayed on the screen, this waste can then be moved around with the users finger. The app needs to use a photo of the users home screen so if looks like they have sneezed on their device.
The louder the sneeze sound trigger is heard by the device the more green snot waste is to be displayed.
The app screen is cleared when the phone or tablet is shaken.
