It’s that time of year again. Sue Barker gets her white pants on, Pimms sales achieve their yearly spike, Andy Murray is either British or Scottish depending on how he’s doing in that particular match, and Serena Williams tries and fails to look even slightly excited about winning her gazillionth Slam. Yes, it’s Wimbledon fortnight, the greatest and most infuriating of world tennis tournaments – and much like this week’s on-court action, there’s plenty of surprises to be had at this topical exhibition.

TAB (Tennis Art Ball), in association with lifestyle website WJ London, are using the opening week of Wimbledon as the time for a pop-up exhibition in which 12 artists of note have done strange things to tennis balls in aid of Greenhouse, a sports and arts charity for innercity children. Such diverse contributors as street artist Pablo Delgado and photographer of the strange Juno Calypso have got up to mischief, and the results are wildly different, ranging from a yummy sundae to a slightly scary flesh-coloured mouth ball – with all sorts of strangeness in between. There’s an auction this very night (27th June) at 63 Broadwick Street to raise funds for Greenhouse, and there are even cake tennis balls from Emma Cakehead on sale. Not as healthy as strawberries but a damn sight more fun.
