We, humans, look rather different from the Earth, but deep down, Earth’s DNA is analogous to ours. To reach the earth closest to her home, I need to remove the tiles on my doorstep. The tiles covering this layer of earth shows a nature in us that is more dominating, the deepest character in all nature: symmetry. We play with symmetry all around us as a rule of life: it starts way before you enter your doorstep and continues at our highest level and biggest scale.
