This is a small "excerpt" out of a series made on a single graphite on paper work consisting of six such tiles (each approximately 8cm x 8cm). I ended up with triangles of varying sizes: I had started with straight lines at an angle of 30 degrees from the edge.
Symbolically speaking, triangles are representations of the natural elements, or in Christianity and other religions, of the concept of Trinity. I prefer, and rather like the idea of the upward pointing triangle referring to the Spiritual and the downward pointing one to that of the Physical realms.
Still searching for something that would go with the Unity of the Spiritual and the Physical.
