It's not actually pictures from each satellite, surely?
As I understand it, they take a model of what the earth looks like in day/night (gained from a collage of photos, certainly not from most satellites), and then rotate it to get the perspective from a particular position; that of your chosen satellite. You could make up your own satellite and get the same result, just by specifying the orbital elements.
No weather, not really up-to-date, no "real" pictures from your favourite satellite. It still looks cute though
