Recently I installed this App on my G1. What it does is that it changes the background image on the home screen with images from webcams around the world. You can choose from many different locations, everything from the Eiffel Tower, Ground Zero,  giraffes in a Zoo, to a laundry room in Japan. It updates every 20 minutes, you can chose what camera you want to watch or let the application randomly pick on. The image quality from a lot of the webcams are surprising good, especially the once from NASA of the sun and earth from space impresses me. I have set the application up to randomly pick webcams. I have to admit that I find myself checking my phone more than usual to see what my home screen looks like. Last time I checked it was showing St Peter in Vatican City. This application is more interesting than I thought it was going to be, highly recommended
