2013 – Population Density Emerging from Walls

Two Yale architects created a room-sized physical visualization of world population density folded into itself:

Hsiang and Mendis then turned that spatial visualization into a physical installation at the 2011 Chengdu Biennale in China. They modeled the population distribution of the entire world in a kind of inverted map that visitors could walk into, inside a 10-by-10-by-10 foot room, with North America on the ceiling, Asia on one wall, Africa on another (see also the little boy in the above photo):
