Yesterday, London's Design Museum opened the largest exhibition it has ever held: Zaha Hadid: Architecture and Design, which continues until 25 November. This is the first major exhibition in the UK of Hadid’s work. If you missed the BBC London News item on Friday, you might be wondering who Zaha Hadid is. She designed the London 2012 Olympics aquatics centre (revised version illustrated), and her award-winning space-age designs are slowly covering the planet. Worth a peek, if the price is right.
