In a rocky cliff-side, a semi-circle is cut into the rocks with a stylus sticking out. The shadow of the stylus moves over the semi-circle. A figure of an ancient boat on the water with a man on the deck of the ship. Push in on the man and he's holding an ancient time-telling device. Cut to a montage of ancient sundials with shadows passing over them. Fade-in on a model of a brightly lit house in a dark forest. Inside the house a small flame moves through a track, burning through strings and causing weights to fall from an early time-telling device
