SurveillanceSaver is a screensaver for OS X and Windows that shows live images of over 400 network surveillance cameras worldwide. A haunting live soap opera.
Download from google code.
It's actually a pretty cool screensaver, you can look at many parts of the globe all times of day and some of the cameras are pointed on marketplaces, others on pigs, computer labs, outdoors, etc. It's a live video snapshot of a bunch of different places around the world. It also tells you the Country, City and Lat/Long of each feed as they show up.
I wonder how many people who regularly visit these locations know this application exists. I haven't seen my lat/long show up yet.
