Four elegant blown glass orbs that contain assembled clock works hang from fine chain in this unique wall sculpture by John Paul Robinson.The elegant orbs in four sizes are defined by a deliberate, fine craquelure and hang at staggered lengths from o-rings and an antique hook. The shadows cast by the piece create a lace like effect on the wall. Sculptor Robinson is well known for using glass and metal to build metaphorical symbols of time, space, earth, fire and water. Here the artist plays with the concept of time and old technology challenged by new ones based on the mathematics of quantum mechanics: "Quantum experiments suggest that it is the past that is determined by the present, not the other way around." This contemplative work is a visual metaphor for this compelling discussion.
