By very carefully feeling the balancing point of each rock he handles - a process that requires awesome skill and patience - Gray is able to arrange them in ways that seem incredible. 'The trick is putting together stones which look like they couldn't possibly sit on top of one another. Only then can you you make something extraordinary' , Gray explains.
All the stones in these pictures are balanced, strictly without the aid of adhesive, pins or computer manipulation. They remain in place through the natural force of gravity and friction. ‘Nature’s glue’ sustains them in these seemingly impossible positions and it is the capricious natural forces of wind or waves that returns them to obscurity amongst their fellow boulders.
