GeoCam.tv is a Google Map of webcams from around the world. The site has recently added live streams from Qik.com. The videos from Qik.com are real-time video streams from users' mobile phones.
What I like about GeoCam.tv is that all the webcams can be viewed directly on the map. Currently the map shows over 1000 webcams from around the world, as well as the live Qik.com feeds. To view a cam just click on a map marker and the webcam image will open in an information window.
