A company called UrtheCast is going to bolt a pair of high definition video cameras with big zoom lenses onto the International Space Station. These cameras will send down live video of Earth 24/7, with a resolution comparable to Google Earth. In other words, you’ll be able to see yourself waving. From space.
I’m not sure I really dig what they used for their “live video” tagging feature, but I do like their they’re going with this.
