Events picks of the week

Cosey Complex, London Consider Cosey Fanni Tutti: artist provocateur-cum-porn star and co-founder of the cult art band Throbbing Gristle. That's the premise of this "Day Seminar/Night Club", co-organised with experimental wordsmith Maria Fusco at the ICA, the gallery where Cosey first caused a rumpus back in 1976 as part of COUM Transmissions' legendary Prostitution show. An impressive roster of artists, writers and thinkers will assemble to explore Cosey As Methodology, including Diedrich Diederichson, Gerard Byrne, Clunie Reid, Martin Bax and Babak Ghazi to name a few. When night falls, a lineup featuring producer-DJ legend, Andrew Weatherall and bands Factory Floor and Fixmer/McCarthy, promises a mix of primal electronic and post- punk sounds for a suitably Cosey knees-up. ICA, SW1, Sat, visit ica.org.uk Skye Sherwin World Pooh Sticks Championships/British And World Marbles Championship, Little Wittenham/Tinsley Green It's a bumper week for gentle-yet-competitive pursuits, with two contests offering a chance to be crowned as a world champion but still make it home in time for tea. First up is Winnie The Pooh's favourite sport, involving dropping a stick into the river from one side of a bridge and seeing whose emerges first from the other side. Slightly more likely to make the 2012 Olympics is competitive marbles, which has been played at this site in Tinsley Green for over 75 years. Days Lock, Sun, visit pooh-sticks.com ; The Greyhound, Fri, visit britishmarbles.org.uk Iain Aitch Camouflage, Manchester A celebration of 95 years of the use of camouflage in warfare with displays and events dedicated to the deceptive attire. Learn the history behind it, discover how to hide a fleet of battleships, and find out the circumstances where a Jeep would be painted pink. There's a trail taking in sites such as a first world war trench mortar, plus an action station where kids get the opportunity to try camouflage gear for themselves. Highlight for many, though, will be the huge, sand-coloured cold war Russian tank captured by British forces in Iraq in 2003.
