http://www.chatroulette.com/ Chatroulette works by connecting two users in a chat. Once you log onto the site and click "Start!", you don't even have time to fix your hair before you're staring at another living, breathing person. You can play using a cam + mic, or either just a cam or mic. Or neither. You can broadcast music/video/pictures. Personally, i use cam, mic a wig and lollipops :3
I'm not sure how I feel about Chatroulette, because it's definitely entertaining, but equally twisted and bizarre. It's a swath of the internet's usual suspects: guys jerking off, Asian kids up late at night, a circle of stoned friends tooling around, and the token curious bystanders who get all of the aforementioned stuff shoved into their face without warning. It's like channel surfing bored or horny peoples' living rooms. Wearing a shirt and not masturbating put me in a minority. NSFW, take note and know you'll run into some weirdos/trolls, esp if your a girl.
Read the directions, and directly you'll be directed in the right direction.
