Summary

Description Description from source: "Harry Lewis '68, AM '73, Ph.D. '74 poses with his senior thesis project, SHAPESHIFTER. The program ran on a PDP-1 computer equipped with graphical displays. As Harvard Magazine described it at the time: 'The program accomplishes rapid transformations in the complex number plane, and allows the user to quickly visualize the results of a specific mathematical transformation. The transformation equations are inputed [sic] to the computer by means of a drawing "pen" ... and converted into machine-recognizable code. The actual computations are then controlled by this code.' "
