I found a link to webpage about a shopping center in the Bay Area that has been demolished and being rebuilt with mixed use properties. There is a live webcam for the construction project. While there isn't much to see yet, the web camera is pretty interesting. You can take control of the camera and zoom in on the Denny's across the street and see people eating. Ok, so it's a little Big Brother-ish but fun to play with. Here's the web cam.
