Circle was a Swedish-based Amiga demo group formed in may of 1993 by Schizo from Noxious, Colorbird, Some1 and Prime from Scoopex. The lifespan of Circle was short, however, as both Colorbird and Schizo later in the year moved on - first to join Alcatraz, then to form Illusion. Most members of Circle later wound up in Illusion, and then eventually Razor 1911. Among the ones that moved on to Illusion were at least Lionheart (ex Insane), Some1 and Prime. As a consequence, Circle died.
