The life and work of artist George Wyllie

One of Scotland's best-known artists, the sculptor George Wyllie, has died at the age of 90.

Mr Wyllie will be remembered for his giant public art, such as the the full-size Straw Locomotive, which he suspended from a crane, and an 80-foot Paper Boat.

BBC Scotland's arts correspondent Pauline McLean looks back on his career.
