Since 2016, artist and woodworker Larry Marley has been building and designing gravity machines. With each version, the design becomes more ambitious and thoughtful. It is a pleasure to watch the hypnotic movement of the balls from start to finish and the gorgeous sound of metal balls on a wooden walkway.
He begins his work with a sketch. Once the design is clear, a mechanical drawing of the "apparatus" is produced. All measurements can then be entered into the software he created to process this information and a list of abbreviations created. The pieces are then cut, assembled and “sculpted” to the final shape.
