Quackeyboard

Makes quacking sounds when you type. It'll work even if the program isn't in focus!

By clicking it you can toggle to three settings: a gradient of pitched sounds (low pitch on the left side of the keyboard to high pitch on the right), random pitches for all keys, or you can turn it off (but if you do, the duck will be sad).
