Dull Doors and clever games

Displaying a selection of Tate's latest acquisitions, this small exhibition is named after a work by Carsten Holler, the artist responsible for the slides in Tate Modern's Turbine Hall.

Sliding Doors is an earlier, more dull work. It features a series of mirrored doors and empty compartments. It's interesting only if you're excited about seeing yourself in infinite regression. Or if you're an artist excited by inclusion and interaction, buzzwords for museum curators everywhere.

Conceptual and visual ambiguity are the themes here, and more conceptually and visually compelling are photographs by Sharon Lockhart and Tim Lee. Lockhart's apparently identical diptych shows a child and a woman completing a jigsaw. Mundane - except the child is an eerily realistic sculpture by Duane Hanson and the photos are almost imperceptibly different from each other.

Facing Lockhart's work is Lee's. Tied to a chair while holding a book by Robert Smithson (an influential artist preoccupied in his early work with mirror-images) Lee is suspended upside down and the image turned to 'upright', while Smithson's reflected image on the book is also 'righted'. Delightful game-playing.

Until Apr 22, Tate Modern, Bankside SE1, daily 10am to 6pm (Fri and Sat to 10pm), free.
