I had this idea for a little app that locks your keyboard and mouse so you can clean them with out worrying about pressing buttons or anything. I have no idea if this sort of thing already exists but I wanted to get it off my chest so I spent the last week making it. I'm pretty happy with it although I did run into some issues like some key combinations can't really be overridden and what not. I still think it's useful and kinda cute to just play with. My wife also had the idea that it might be good for parents who work from home and need to leave the computer for a moment to go to the bathroom or get the mail or what ever. If they put on Key-B, they won't need to worry about their kids messing with the desktop or anything. Now that I think about it, it could work against cats who like to walk on the keyboard too.

Oh also, I wanted to mention that I used ChipTone by SFBGames to make the sounds so thank you for sharing such a great tool!

That's about it. I hope you enjoy :)
