Sculptor, photographer and mathematician Kenneth Snelson has commented, “My art is concerned with nature in its most fundamental aspect, the patterns of physical forces in three dimensional space.” B-Tree II is a site-specific commission that—while concerned with nature—firmly utilizes geometry, mathematics and engineering in referencing the natural world. Based on patterning systems using the number three and triangles, the colossal structure utilizes the artist’s patented “tensegrity,” wherein the carefully calculated tension of the stainless steel cords locks the tubular elements up and into space. B-Tree II is the largest structure Snelson created.
