High Quality Content by WIKIPEDIA articles! Scalos is the name of a commercial (then freeware) desktop replacement for the Workbench Amiga original GUI, based on a subset of APIs and its own front-end window manager of the same name. It was originally written by programmer Stefan Sommerfield for a software house called AlienDesign in November 1999. The purpose of Scalos was to recreate the mouse-and-click experience on Amiga, an alternative to the Workbench interface present in versions 3.0 and 3.1 of AmigaOS (then considered obsolete). The actual developers are a small group of English programmers known as Satanic Dreams Software. As stated on its website, the name "Scalos" was inspired by the time-accelerated planet Scalos from the Star Trek TV series` fictional universe.
