Upon last check of the Android market, there are over 4000 applications and games in total. One strange and interesting app that I've come across lately is called FaceIt. FaceIt is an app which listens to sound from the phone's microphone and shows a mouth which opens based on how much sound it's hearing.

I tested the app out and found it to work exactly as described. There are several different faces including the ubiquitous smiley face as well as a cartoony ogre, vampire and clown. I think this is an excellent app for kids to play with. The responsiveness is good and the UI is simple, providing only a menu to change the face.

Even though the functionality is limited, an app like this shows the different and interesting uses of the Android platform. I probably won't be a regular user but I think it's creative and a good app for playing with a baby or letting kids use. I was initially skeptical that a child wouldn't be freaked out by this but I tested this with my friend's baby using the clown face and it actually worked, making the baby laugh.

If you have a baby or young kids, I'd definitely give this a shot to play with them.
