Webcams date to an earlier era of the Internet: the very first one, in 1991, was pointed at a coffee pot in a computer lab at Cambridge University. But the tradition lives on in various corners of the web, which comes in handy when, say, an enormous storm is barreling toward the East Coast of the United States.
The webcams listed below should provide a good view of Hurricane Sandy's arrival in New York City, on Long Island and along the Jersey Shore. Tell us in the comments if you have any others to add to this list.

Lastly, while this isn't a webcam, Instacane is a great, intimate view of how people are experiencing Sandy as documented on Instagram.
