The medieval Welsh town of Conwy is transforming the walls of its historic buildings into giant cinema screens for the blinc digital arts festival.

The festival, the biggest of its kind in Europe, sees a range of computer projections from abstract patterns to David Cameron displayed on walls throughout the town, turning it into a huge outdoor gallery.

Among the themes for this year's festival is the mathematician Alan Turing, who is credited with cracking a German code which helped end WWII.
