Andrew Graham-Dixon looks back over the best of the year in art. Highlights include a major show from Japanese artist Yayoi Kusama, whose dazzling body of work creates a unique world of colour, pattern and shape. Also, Florence Welch, a pop star who brings the great themes of the Renaissance into the 21st century, joins Andrew for a tour of the National Gallery to share some of the art that inspires her.
Michael Smith takes a night-hike up Arthur's Seat in Edinburgh with hundreds of runners wearing specially-designed light suits, creating a mass act of light and colour on the city's famous hill. Also featuring highlights from this summer's London 2012 Cultural Olympiad, including a rooftop sculpture which recreated the legendary final scene in cult movie The Italian Job; a spectacular underwater wheelchair performance; and an experiment in learning with artists Michael Landy and Bob and Roberta Smith, who turned an art gallery into a classroom and let the artists take charge of the lessons - with eyebrow-raising results.
