In Escalator, Vidya Gastaldon presents a vision of the rainbow: a short and elusive experience, which she tries to recreate within an enclosed space. Escalator isnâ€™t a drawing, nor a painting, nor the usual sculpture: itâ€™s an actual rainbow made of wool. The rainbow lies at the heart of so many stories, one being â€˜The Wizard of Ozâ€™. Vidya Gastaldon acknowledges that there is a reference to Dorothy here, in particular to when the unhappy young girl wants to escape to the beautiful place thatâ€™s over the rainbow. Gastaldon miraculously transforms the rainbow into a soft, woollen rainfall, as if Dorothyâ€™s desire â€“ and that of the child within us all â€“ had finally been granted.
