A number of years ago a friend and I sat on the beach watching a man quietly and patiently balancing rocks on top of each other. It was mesmerizing. This is a craft that definitely has a Zen quality to it.
Rock balancing uses no adhesives, wires, rings or other supports to help maintain the rocks' balance. Many rock balancing artists consider their craft a practice of awareness and mindfulness. Although there are some who feel that rock balancing wreaks havoc in national parks, this is certainly a mindful practice that can be done in private spaces.
