The Undo function negates the last command done on a computer interface. With it we gain  timelessness, a licence to be messy and take risks while interacting with software. Created as a physical ode to digital graphics, Undo neatly layers attractive patterns but forgoes any compositional hierarchy: the planes obscure and cut into one another, scraped off in playful “eraser” marks. With no steps backwards to go, the canvas is preserving the illusion of perpetuity by being limited: a disrupted arrangement, a permanent transient state.
