A huge art installation by Ghanaian artist Ibrahim Mahama, enveloping a side of London's brutalist Barbican centre in swathes of purple cloth is unveiled in London. "Purple Hibiscus", named after Chimamanda Ngozi Adichie's eponymous 2003 novel is 2,000 square metres (2,1528 square feet) of purple panels with traditional Ghanaian “baktari” robes hand sewn into the fabric. Speaking to AFP, Mahama says his artwork - so big it needed to be crafted in a stadium - highlights “what labour actually means in the century we live in”, adding he thought grey London could do with something to “brighten it up”.
