Stretch provided Aldo Giorgini (1934-1994) with a framework for manipulating vector primitives using his own mathematical model. Although stretch was technical report in 1981, Giorgini had a prior body of work in 1976 that demonstrated the use of stretching algorithms to make art, like in the case of inedited works such as checkerboards, stripes, polka dots and swiss cheese. After exhaustive primary source research at Giorgini’s estate in Lafayette, Indiana, there was no evidence that the manuscript for Stretch was actually published. However, the Stretch framework was found in a manuscript stage and this paper will unveil the methods that Giorgini created for his own artistic production. The program was written in Fortran IV and intended for a CDC-6600 computer.
