“Phoebe’s playground” is composed by a physical installation of a minimalistic square “garden” 3*3 , covered with sand. Two rocks and one tree stump (70*70 cm) are placed on the sand. The installation requires a wall in one of its sides to place the light source (moon) 
Arduino sensors will be incorporated in the rocks (heat pad sensors) and stump (a fan).
There will also be 2 required headsets.
A small extra space for storing backup materials for the sensors and charging will be required.
