Penguin Software's core products were its graphics programs that were among the industry best-sellers of the early 1980s. "The Complete Graphics System", first published in 1981, was a set of drawing and 3D graphics editing programs for the Apple II by founder Mark Pelczarski. "Special Effects", co-written by Pelczarski and David Lubar later the same year, helped establish the company's slogan, ""the graphics people"". In early 1982, Pelczarski, Lubar, and Chris Jochumson created "The Graphics Magician", which would define the next several years of the company's evolution. "Graphics Magician" was aimed toward developers or anyone wanting to be a developer, allowing any programmer to create animations for arcade-style games and compact graphic images for adventure games and educational software.
