In ‘Wipeout’, Liddy Scheffknecht uses sunlight and an everyday object – a sponge – as sculptural material. The light that shines through a window is cast into a specific shape – the traces of a sponge – by silhouettes attached to the window. By uncovering and moving the hand with the sponge simultaneously, the sponge becomes a painting or cleaning tool, applying sunlight to the surface, or revealing it.
