Bath-based 'Professor' Mervyn Heard recreates the kind of frightening magic lantern performances full of ghosts and monsters which were seen back in Brunel's day - long before the days of cinema. In the past Mervyn has created special presentations for Tate Britain, the Royal Opera House, Highgate Cemetery and other specialist venues, in many different parts of the world.
