我们共有八十亿人，几乎都聚集在横跨南亚与东亚的同一条狭窄地带。地球随城市的昼夜节律而脉动，每一次维基百科的实时编辑都点亮其上。一棵展示每一种已知语言的树。一片点云，其中每个点代表一千人。让人口统计成为可以感受的东西。
A live atlas of how many years of school a child can expect — 47 nations ranked, racing up the decades, with the schooling-versus-wealth story laid bare.

城市随人类的昼夜节律而脉动——人们入睡时区域变暗，醒来时变亮；维基百科编辑的闪光在各语言区域的中心点亮起（并非确切的编辑位置）。

The age-sex structure of a nation as a back-to-back pyramid — scrub the decades and watch the shape morph from a broad young base to a top-heavy graying spire.
A bar-chart race of adult literacy across five decades — nations hauling themselves from a third of adults reading to nearly all of them, with the 90% summit marked as each one crests it.

The demographic transition drawn live: every nation a dot on a births-versus-deaths plane, the gap between them its natural growth — watch booms swell, mature, and slip below the line into shrinking as the years roll by.
地球上的每个人都是一个像素粒子（1:1000 比例）。八十亿个点，几乎全都集中在横跨南亚与东亚的一条狭窄地带上。
