What is the webcam used for?

The web cam is used to take pictures, videos and many other things so you can make movies, connect with people over the Internet who could be even in another country, or go on Chat-room Roulette [lol ;)]. The web cam is also GREAT for people who are deaf or mute, as they can use sign language to communicate, because they can't hear the phone ring and they can't talk to peoples.
