As babies smash on the keyboard, colored shapes, letters and numbers appear on the screen. Baby Smash will lock out the Windows Key, as well as Ctrl-Esc and Alt-Tab so your baby can't get out of the application. Pressing ALT-F4 will exit the application and Shift-Ctrl-Alt-O brings up the options dialog.
There's lots of options to explore that change the way BabySmash! works. You can have the shape laugh or anounce what they are like "Blue Square!"
You can set how many shapes fill the screen before it clears.
