In Jim Rosenberg’s diagram poems a graphical notation acts as an external syntax — thereby, as Rosenberg puts it, “allowing word objects to carry interactivity deep inside the sentence.” This interactivity allows each element of the syntax to be occupied by complex clusters of words: layered, multiply embedded, and yet legible. Rosenberg’s earliest experiments with diagrammatic poems date back to 1968, and he has been creating interactive works since 1988, using a variety of platforms. Diagrams Series 6 was developed in Squeak, an environment that allows for reading on a wide variety of operating systems and also enabled Rosenberg to move (for the first time) to composing each poem in the series within the interactive reading environment.
