I chose this knot as one of the representative symbols for the gallery window as it clearly shows the basic rules of knot creation: 1) an alternating over / under pattern 2) with no angle corners intersecting lines and 3) radial symmetry.
Here is the same knot, just for fun, graffitied on metal.
The final piece was done on charred wood with a technique which makes the knot visible only at certain angles and certain lighting conditions (chatoyancy). In direct sunlight, the knot is barely visible until a shadow falls on it.
The position of this piece in the gallery actually lines up with the window at a certain angle from outside.
