One art installation, which the pair had commissioned by a local artist, has proven especially delightful. It consists of three red steel cubes elevated on poles, with the tallest cube at 22 feet high. “Shortly after they were installed we were out in the garden and heard an unfamiliar, gong-like sound. It turned out to be caused by the steel expanding and contracting with the changes in weather,” explains Alessandrini. When the artist heard about the phenomena he offered to drill holes in each cube to make it stop, but Osterling and Alessandrini refused. They enjoyed how the unanticipated sounds added a new layer of auditory experience to their garden.
