Children are attracted to computers. They love the blinking lights, the computer screen and the changes that happen on that screen. It does not take long before they realize that pushing buttons on the keyboard might have an effect on the computer screen. Adults usually do not think that something bad can happen if their children hammer on the keyboard but they sometimes find the killer combination that does something unexpected.

Crazy Little Fingers steps in and offers a rewarding experience for the child while keeping the computer and the data safe. It is a fully portable application that assigns images to keys on the computer keyboard disabling all other keys that are not assigned. If a child presses a key an image is displayed, the image can be anything as it is possible to exchange the default images with others.

This can result in some interesting experiences. It is for instance possible to create a set of A-Z and 1-0 images that show the letter or number and something that begins with them, say an apple for A, a bee for B and so on when the key is tapped on and the program is running.

The author mentioned sounds in the introductory post but those do not seem to be implemented yet. It would be nice to be able to combine images and sound so that pressing a key would display an image and play a sound at the same time.

There is one key combination to get you out of the state. Pressing [CTRL ALT DEL] will remove the lock and disable the application.

We have covered a similar application before: Toddler Trap suppresses the keyboard and mouse when activated. This is not that rewarding for the child however.

    Also very handy when you want to clean your keyboard without interfering with whatever it is your computer is doing at the time :-))

    How about something that gives a little electric shock as soon as the little blighters touch the keyboard?
