Helen Mark explores landscapes of the future, of the imagination and of the past, at the Great Exhibition of the North, which is centred in Newcastle and Gateshead. It's a three-month celebration of the impact of northern England's creators, inventors, artists and designers.

Helen meets environmental artist Steve Messam to hear his sound sculpture 'Whistle', a series of steam engine whistles echoing around the city walls. There's Naho Matsuda whose 'data poetry' is created by people's interaction with the cityscape and displayed on a split-flap display board at the Theatre Royal in Newcastle. Helen will follow one of GetNorth's story trails with the multi-award winning author David Almond and investigate public transport of the future with Sophie Connor of Ryder Architecture. And she'll find out how local children respond to highlights of the exhibition.
