From the automaton description:
A new one-off piece by Paul Spooner. With echoes of Picasso's cubist painting 'Seated Bather by the Sea' (1930) Spooner's chair has 8 fingers which move like a wonky Peter Markey Wave Machine. The piece is operated by batteries (included) and the fingers start moving when the knob on the drawer is turned. Oak and mahogany (recycled from hospital).
