"For Earth Day we are trying to create an image of Earth from the ground up, while also fostering a collection of portraits of the people of Earth. Once those pictures stream around the world on Earth Day, the individual pictures tagged #GlobalSelfie will be used to create a mosaic image of Earth.
So come April 22, take a second to step outside and join us in celebrating our home planet. The Earth mosaic image itself, and a video using the images, will be put together and released in May."
