Check this out... you can access each camera individually and pull up a live stream. Santa Clara Traffic Cams.
Here's a direct link to one of the live streams. This is a camera that is showing the Montague Expressway and Great Mall Pkwy/Capitol Ave intersection in Milpitas. Anyone from around these parts knows this spot. But, did anyone know that you're on camera when you're there?

More traffic camera fun... here's a live stream (updated every 2 seconds) of the Las Vegas Blvd / Flamingo intersection in Vegas. (Bah... you have to click the image, which takes you to the main web site to view it. Still pretty cool though.)
