You're in the heart of a densely-packed city. But that doesn't mean that you can't exercise. No, I don't mean the elliptical trainer in the corner. You can actually get outside and play sports while surrounded by skyscrapers.
JC Deceaux, Florian Brillet, and Nicholas Lelievre created an interactive art installation called Mens Sana in Corpore Sano (Translation), which is Latin for “A sound mind in a sound body.” It consists of sporting equipment built into street signposts. The three artists are doing this to encourage people to get fit at times when it seems like there are limited opportunities to do so.
