Earthsim is one of the few 3D screensavers and browsers aimed at high-end PCs, and features some of the most detailed and best-presented space views modelled so far on a home PC. This shareware screensaver version shows stunning up-close flybys of the Earth and Moon complete with breathtaking sunrises and sunsets, and includes a sample 3D documentary about the Andes mountain range. The simulation has realistic atmosphere modeling, real-time sun position, and high-resolution NASA images of Earth, with accurate orbits, orientations, and star field. Earthsim works as a full-screen browser and updates using the Internet to get new content and live data, updating every six weeks.
