John Muir talked about the mountains as nature's cathedral, a secular but sacred place. That sense of a cathedral can be seen in a canopy of trees when the branches of old oaks arch over a walkway. Regent's Park has been the setting for secular and sacred occasions for hundreds of years, as one of London's Royal Parks. The unpredictable patterns and long forms are examples of biomimicry, casting dappled light onto the carriages and walkers below. This pattern can be installed in alternating directions to show this connected arch quality.
