The actual physical space of an exhibition, the last major component presented in this book, works in concert with the exhibition’s content and 2D design. Space is not a static medium, but is active in the creation and development of meaning. A visitor’s interaction with space is a kinetic experience, engaging the whole body and accounting for movement through and within, and should be considered with the added fourth dimension of time. Time and space go hand in hand; it is a matter of not only knowing how a visitor interacts within the exhibition experience but also when and for how long. McLean (1993, 121) describes this as “pacing;” in other words, “the consideration of a visitor’s movement through and interaction with an exhibition over time.”
