The sand trapped in a vertically symmetrical glass tube inevitably runs out. As the sand flows down through the glass tube, the weight and friction gradually decrease the amount of sand. Eventually, one side of the glass tube becomes devoid of sand. However, paradoxically, the inverted hourglass signifies a new cycle of land and sky, voids and solids, facing each other.
We destroyed and abused nature for convenience. As a result, humanity lost its footing. To survive, it returns to a primitive form that conforms to nature. Like an hourglass with absolute time and flow, it receives a constant supply of natural moisture. They acquire only the amount of resources they need and embrace a new ecosystem that contrasts with our existing lives.
