[2] Created by Nick Park of Aardman Animations, Shaun the Sheep is an unusually clever sheep who first appeared in the 1995 Oscar-winning short film A Close Shave, helping Wallace and Gromit to rescue his flock from being turned into dog food by a malfunctioning robotic dog.
In 2014 he was voted the nation's favourite children's television character in a poll conducted by the Radio Times and the British Film Institute.
The charity also launched a dedicated Shaun in the City Youtube Channel, showing films promoting the trails and app, interviews with celebrity designers including David Gandy, and behind-the-scenes videos of artists at work.
The Bristol trail launched on 2 July 2015, with Shaun the Sheep creator Nick Park driving a vintage tractor across Clifton Suspension Bridge, pulling a trailer containing several sculptures.
[10] Wallace & Gromit's Grand Appeal and the digital team at Aardman Animations developed an interactive app called Shaun in the City: Sheep Spotter for the two trails, available for Apple and Android devices.
