the basis for a next-generation carrier class long-distance telephone switch. The Graphics Division's Craig Reynolds devised an algorithm that simulated the flocking behavior of birds in flight. Boids made their first appearance at SIGGRAPH in the 1987 animated short "Stanley and Stella in: Breaking the Ice", produced by the Graphics Division. Reynolds went on to win the Scientific And Engineering Award from The Academy of Motion Picture Arts and Sciences in 1998. The Symbolics Document Examiner hypertext system originally used for the Symbolics manuals- it was based on Zmacs following a design by Janet Walker, and proved influential in the evolution of hypertext. Symbolics was very active in the design and development of the Common Lisp Interface Manager (CLIM) presentation-based User Interface Management System. CLIM is a descendant of Dynamic Windows, Symbolics' own window system. CLIM was the result of the collaboration of several Lisp companies. Symbolics produced the first workstation which could genlock, the first to have real time video I/O, the first to support digital video I/O and the first to do HDTV. Symbolics Graphics Division The Symbolics Graphics Division (SGD, founded in 1982, sold to Nichimen Graphics in 1992) developed the S-Graphics software suite (S-Paint, S-Geometry, S-Dynamics, S-Render) for Symbolics Genera. Movies This software was also used to create a few computer animated movies and was used for some popular movies. 1984, graphics for the little screens on the bridges of the Enterprise and the Klingon ship in Star Trek III: The Search for Spock 1985, 3D animations for Real Genius 1987, Symbolics, Stanley and Stella in: Breaking the Ice 1989, Symbolics, The Little Death 1990, Symbolics, Ductile Flow, presented at SIGGRAPH 1990 1990, 3D animations for Jetsons: The Movie 1991, Symbolics, Virtually Yours 1991, 3D animations for An American Tail: Fievel Goes West 1993, 3D animation of the Orca for Free Willy References Further reading External links The Symbolics Museum Archives from the Symbolics Lisp Users Group (SLUG) Mailing List, 1986-1993 Archives from the Symbolics Lisp Users Group (SLUG) Mailing List, 1990-1999 Ralf Möller's Symbolics Lisp Machine Museum A page of screenshots of Genera "Genera Concepts" – Web copy of Symbolic's introduction to Genera A collection of press releases from Symbolics "Symbolics announces the first true Single-Chip Lisp CPU" – Symbolics press release announcing the Ivory chip Lisp machines timeline – A timeline of Symbolics' and others' Lisp machines Kalman Reti, the Last Symbolics Developer, Speaks
