Sphinx's thirteenth intro, released in December 1989, with code by Flex and charsets contributed by both Unitrax and Apollyon. The music is EVS's "So-Phisticated III (part 3)" by Edwin van Santen, preserved in the HVSC under the 20CC directory — linking Van Santen to the Dutch group 20CC. Founded in the Netherlands on 8 May 1988 under the tagline "Reflection of Perfection," Sphinx had produced thirteen intros within roughly eighteen months. An earlier Sphinx intro appears at #787 Sphinx-07, released in June 1988 with code by Grimlock and music by Mike (Michael Hendriks). The transition from the Grimlock/Grayhound/Mike team to Flex/EVS between 1988 and 1989 illustrates the membership evolution typical of active Dutch groups. Doc Snyder's page documents three Sphinx intros with credits spanning multiple contributors. The Atlantis Prophecy archive contains an interview with the group, providing additional historical context.
