oh-OH is a simple gesture - telegraphing the memory of a wedge of swans swimming on open water - using the most economical means possible. The folded forms recall minimalist artists like Judd, but there is humour and pathos in the colour and spacing of the pared down elements, which counters a reading of this as simply austere minimalism.

Baltes, is a Berlin-based artist known for her paintings and installations that stand on the edge of abstraction and figuration. In this new move into outdoor sculpture, she stays true to her practice language that utilises edited, defined shape, block colour and abstraction.

The brightly coloured components, made from powder-coated steel are set into a baseplate that preserves the spacing. This can then be submerged under the water, so the elements appear to float.

Cornelia Baltes (b.1978, Germany) graduated from the Slade School of Fine Art; London in 2011.
