Polymorphic is a kinetic and interactive installation utilizing an innovative design and engineering solution inspired by the simple kinetic action of a see-saw and the reverberating motion of a Slinky. With a series of 119 unique and interconnected sections, a simple central pivot and bolt system allows the vertical movement of one section to be picked up by others down the line. Together, this motion allows the installation to transform from a series of leveled sections into an undulating form activated through interaction with its occupants.
