KeyWack X for Mac Free download

EditByBSEditor: KeyWack is a game for people with babies and small children who like to sit at their parent’s computer and bang the keyboard. KeyWack prevents babies from accidentally opening most programs or documents, and makes banging even more fun by drawing shapes and playing random sounds as the keys are whacked. You can also click with the mouse to place a shape at a particular location.

Optional toggles include:

Limit display to counting through numbers then letters to teach kids (Command-K)
Rotation of letters & numbers (Command-R)
Turn the Sound off (Command-S)
Wipe the screen of images (Command-W)
About Help (Command-A)
To Quit KeyWack type Command-Q or Control-X.
