Chatroulette is a website that pairs random strangers from around the world together for webcam-based conversations. Visitors to the website randomly begin an online chat (video, audio and text) with another visitor. At any point, either user may leave the current chat by initiating another random connection.

Now you can get the iPhone version of the Chatroulette that let you Random chat with strangers.  The app is free and was made by SKJM. It uses the iPhone 4's front camera and makes an ad hoc connection with another camera on the network. It works over Wi-Fi.
