Two unknots are arranged vertically above a charred wood base. The shape of the metal (painted aluminum) makes self-supporting convex and concave arrangements possible.
An unknot is a simple, closed loop. This particular one has sharp angles, but it still unfolds to something equivalent to a circle.
My interest in the unknot relates to the rules you have to follow to make a knot diagram. A branching path presents a problem when trying to represent the over- / under-lapping of crossing paths: what happens when a path branches? Turning a path into an unknot by using a copy of itself as negative space centered in the branching path removes this problem.
The charred wood of the base resembles embers in light, and glows in the absence of light.
