Elizabeth Sims’ Valediction for a Sunbeam presents a yearlong progression of images and text documenting the movements and meanings of a sunbeam in the school where she teaches art. Using the sunbeam’s amorphic nature as an occurrence to position herself against and within, she interrogates the function of roles and identities, such as that of the teacher. Texts from Tiqqun, the Situationist International, Giorgio Agemben and others are gathered into the de-centered voice of the critique as she looks at how encouraging and perpetuating the sunbeam’s disruptive effect on her workday informs her moment by moment identity within seemingly intransigent systems.
