Virtual Keyboard... Does this exist?

[okayplayer]

I was wondering if anyone knows of a utility that shows a keyboard/keypad on your screen so you can mouse click the #s instead of using the keyboard on your laptop (so I can recline in my chair and play)? I know this makes me sound real lazy, and you could just say get a wireless keyboard, but that's more expensive and cumbersome.

Obviously, I'd like this to not take up much space on my screen.
