We went to see One Two Three Swing! that has just opened in the Tate Modern Turbine Hall today. It definitely has to be the most fun Turbine Hall exhibit in a few years. It has a giant swinging ball, mad stripy carpet and a whole load of swings for three people. Definitely worth the visit, my kids even got a bit of science out of it, with a discussion about how the best swings were the ones with the longest chains, as you could get a bigger swing.
