Imagine your skin, its wrinkles like a valley. Get down and observe the network of cracks on the huge rock walls in the valley. The walls of the cells indicate cavities - feel free to climb into the cave, there you will find plants that feed on the infiltrating faint light. Take a closer look at these plants, their stems and roots. There are small cracks in the roots, these are made up of their cells. Fly in and you can dance with atoms. When the dance of joy is over, there will be nothing there... but wait, there a lot of serpentines there! Everything is there.
