Trover is great ! You can share photos instantly with your iPhone or Android device and literally travel throughout the world from your desk and your armchair. It's easy to use and something that you really should take a moment to see. When you have a little time, visit their fine webpages and crawl through the thousands of travel photos from around the world that are being uploaded at this very moment. I saw one of a woman about to ski through the clouds in a mountaintop in Oregon. Just scroll over the photo to see the point of origination. It's dazzling !
