Its a NASA fun event. You know the folks that track a bajillion sattelites in orbit around us taking pictures of us night and day. They have a fun promotion, game if you will for Earth Day today. Take a selfie, post it with the hashtag #GlobalSelfie and they’ll in turn use all of the images into a giant mosaic of earth.
The subject doesn’t matter, mountains, rivers, oceans, forest…just include you with a sign naming your location. The sign can be downloaded in numerous languages HERE. Your snap then can be uploaded to twitter, instagram or google+ with the hashtag and its on it will get captured for the mosaic.
