One of the first commercially available GUIs. Borrowing heavily from the MacintoshWIMP-style interface it was available for both the IBM compatible market (being packaged with Amstrad' s original PC series) and more successfully for the Atari ST range. The PC version was produced by Digital Research (more famous for DR-DOS, their MS-DOS clone), and was not developed very far. The Atari version, however, continued to be developed until the early 1990s and the later versions supported 24-bit colour modes, full colour icons and a nice looking sculpted 3D interface.
