Bringing the Wandsworth Arts festival to a spectacular close, the Shimmy is a collision of family-friendly site-specific arts pieces from the likes of Battersea Arts Centre and Emergency Exit Arts plus free workshops and fun activities. It’s all a bit mysterious, but last year’s involved a huge conga, a community-made kilometre of silk bunting and spectacular performance and dance pieces. St Mary’s Church Square. Free. Sunday 1-5pm.
