Other elements to the production were done by a variety of BBC designers. The Heart of Gold and B Ark models were built by Perry Brahan. The small, furry creature from Alpha Centauri in episode three was a puppet designed and controlled by Jim Francis, who also built the Magrathean bubble car (also seen in episode three), and was the stunt double for Richard Vernon in the scene in which the bubble car was seen to fly. Matte paintings throughout the series were created by Jean Peyre. Music and sound effects were by Paddy Kingsland, with the exception of the theme music; the familiar "Journey of the Sorcerer" theme by Bernie Leadon was used again, in the arrangement by Tim Souster that had previously been used for the "Hitchhiker's" LP. Video effects using the Quantel system were done by Dave Jervis. Other puppets, including insects seen in episode five, were designed by Susan Moore. Some of the actual puppeteering was done by Stuart Murdoch, including operating parts of the Dish of the Day animal.
