Trees of life
A rope structure is stretched between several trees and rows of aircraft oxygen masks are hanging on it. The sight of pending oxygen masks in a flying aircraft would mean an acute state of emergency. In a forest, the same visual experience loses this concrete meaning, but still, its message gets transferred into the new context. These unnatural objects, designed to save lives, hung in a space, commonly considered to be natural, are ironically hung too high to be reached in case of emergency.
