We observe her as she speaks and then hears her words relayed back to her through a delayed transmission. Remarkably eloquent for one caught in such a feedback loop, Holt provides a monologue on experiencing time, thought, and oneself through technology. She remarks, “I have a double take on myself. I am once removed from myself … we are hearing and seeing a world of double reflections and double refractions.”
