Pendulum 3D Mechanical Wooden Puzzle

This wooden pendulum is a really beautiful wooden set, which you put in a meditation-like state when assembled. The pendulum can be hung on the wall and is driven by a rubber motor which, with the help of a drive weight (lowered lead), is pulled down and thus displaces the pendulum in a uniform motion. The weight can be differentiated (for example with different coins) to set the desired pendulum speed precisely. The pendulum set in motion runs with the many observable parts approx. 120 minutes.
The even rhythm helps him to relax or even meditate and is an absolute peek at every wall.
