If you have little kids, you’ve probably found they love to “help out” at the keyboard. I have a 1 year old who loves to sit on my lap and hit the keyboard, but the right combination of keystrokes can be paralyzing.

So one night I wrote an application similar to Scott Hanselman’s BabySmash mainly to familiarize myself with C# and .NET. It’s called SmashKey.

It starts in full screen mode and for any keystroke you type it prints a random shape and plays a random sound from the system media folder. There’s no configuration or settings, and to exit you go to File -> Exit. It’s portable, but requires .NET version 3.5 or later to run.

If you want a full featured application, this isn’t it, but if you want a tiny and simple application, SmashKey is for you.
