The installation, Forest of Numbers, is composed of 10 layers, each to represent the next 10 years. Figures 0 through 9 create the 4 digits needed for each year. The numbers are also divided into 100 shades to align with Moureaux’s 100 Colors installation series which she has installed around the world since 2013. You can see previous installations from this series on her website. (via My Modern Met)
