If I only had ...

... one piece of artwork to see this week, I'd head to West Kowloon to suss out what is arguably the biggest piece of artistic poo in Hong Kong history: Paul McCarthy's Complex Pile. The 15.5-metre-tall inflatable sculpture, which is part of the ongoing "Mobile M+: Inflation!" exhibition, may be trailing behind in the popularity stakes - Florentijn Hofman's Rubber Duck is the city's clear favourite, judging by the number of snaps of the yellow float posted online - but McCarthy's more cerebral heap is still worth a look in.
