Garth and Bev - Traffic Lights

Animation about a time-travelling brother and sister called Garth and Bev, who live in harmony with nature in their village. They are transported to different times and places by the Time Spiral and solve problems with the help of Grandfather Lir. There's a wedding in Ballybeg and with all the comings and goings, Dermot the Watchman is having a spot of bother keeping order at the crossroads. Garth and Bev discover that in nature, red means stop, and they travel through the Time Spiral to meet Gareth Morgan, who used a similar idea when he invented the traffic lights!
