Pipilotti Rist first came to my attention as part of the Walking in My Mind exhibition at the Hayward. For her work 'Sleeping Room' disembodied organs were projected onto the surfaces of a room while a soothing soundtrack played. The highbrow was delightfully undercut by the fact that a man standing deep in thought was unaware of a penis projected onto the back of his suit.
That work isn't included in this particular exhibition of the Swiss artist's work, but it serves to illustrate that throughout the serious and more complex readings of her work, there's a current of humour and playfulness.
