KeyWack is a game for people with babies or small children who like to sit at their parent’s computer and bang the keyboard or click the mouse.

KeyWack prevents children from accidentally changing programs or documents, and makes banging even more fun by drawing random shapes and playing sounds as the keys are whacked. You can also click with the mouse to place a shape at a particular location.

You can use the program for educational purposes by displaying:
simple math equations
Morse code
HTML codes
City, county and country names
Personal names
Dictionary words (Danish, Dutch, English, Finnish, French, German, Hungarian, Italian, Norwegian, Portuguese, Romanian, Russian , Spanish and Swedish)
Bible verses

It operates full screen, so press Command-Q to Quit. The other options are Command-B (Black/Grey), Command-R (Wipe screen), Command-S (Sounds on/off) and Command-K (Actual letters vs alphabetical order).

Huge disappointment

I installed this for my daughter and after several frustrating minutes of playing with settings, the only way I could get this to do anything was to turn on the option to display ascii characters. My daughter just turned 1 and I’d like her to see the letters and numbers. I’m not at all happy and wish I could get my money back.

Hate it!!!!!!!!!!!!!!!!!!!!!!! ,

Dont waste your money

I read both good and bad reviews. I am not happy with this purchase. Despite the claim, he can still get into other programs. I am constantly having to fight him off, to get back into the app. Waste of time and money.
