We declared a sequential animation group consisting of three animations, each taking one-third of the day length. The first member of the group makes the sun go up. The second member, which is an instance of a new element type—PauseAnimation—introduces a delay equal to its duration. This, in turn, lets the third component start its work in the afternoon to pull the sun down toward the horizon.
The problem with such a declaration is that the sun moves in a horribly angular way, as can be seen in the image.
