Anyone who knows me understands that I live with an all-consuming travel lust. There's nothing I like more than going out to see what else is in the world. It's a prohibitively expensive fascination, so I'm often forced to accept compromises. RoundMe for iPhone (free) is so lovely in its execution and delivery, I'm glad to use it to explore this fine planet of ours.
RoundMe is a network of user-submitted, panoramic photos, which the service calls "Spaces." As version 1.0 launches today, there's a whole host of gorgeous photos available to explore, all submitted by professional photographers. Upon launching the app, I used its map to navigate to Italy, so I could "revisit" some of the places I saw during my honeymoon, like Rome's Piazza Navona.
When you visit a space, you can move your phone in all directions to explore the full panoramic photo. Not all will let you turn a full 360 degrees, but those that do are very impressive. It's a whole lot of fun and I spent a lot of time poking around and exploring both mundane and spectacular sights, from grand cathedrals to modest apartments.
