British artist Tim Knowles takes plein-air performance art literally with his poetic and uncomplicated Tree Drawings created by the branch tips of living trees. Using simple drawing tools attached as freehand extensions to the tips of tree branches and in collaboration with the wind and local weather conditions, calligraphic gestures and automatic drawing readings are recorded on paper. Knowles claims that there is an unmistakable signature that each drawing reveals as an indication of the unique characteristics and even genus/species of a specific tree.
