The second website, by John Walker (founder of AutoDesk), offers the Earth and Moon Viewer, which has the day and night feature, as well as views of the earth from the moon, and the day and night sides using satellite imagery. It is much more of a webmapping interface, with query boxes to change the view and type of imagery.
