Abstract: An omnipositional cable-suspension system suspends an inanimate object. A pair of spaced apart holes pass through the object. A first closed cable loop passes through both of the holes and a first hooking point, so that a first cable is movable within the holes. A second closed cable loop passes through both of these holes and to a second hooking point, so that the second cable is also movable within the holes. The inanimate object can be moved from one position to another, while the object remains stable in any position so placed. This omnipositional cable-suspension system enables the suspension of any inanimate object (the “object”) that can be readily moved to any position about its three-dimensional axis without changing the cable-suspension system of the object. The object can be repositioned to any other stationary position as many times as desired.
