Time will be represented as a wilting flower. Throughout each hour the petals of the flower will fall off and fade away. As the hours pass through the day the stem will warp more and more and drop the flower lower and lower.
Time will be represented by the shadow of a white cylinder on the ground for the twelve hours of daylight, moving from left to right and stretching and contracting, throughout the day. By night, this will invert into a white luster of moonlight on a black cylinder which will move the opposite way through the hours of night.
Time will be represented by a pair of eyes. As time progresses to noon, the eyes will open wider and wider. At noon the change will reverse and the eyes will start closing. Through the passage of an hour, the pupils will move either from left to right on even hours or right to left on odd hours. Every 3 seconds the eyes will blink.
