With no beginning and no end, the circle is an ancestral sign of God, the Sun, and Eternity.
Although geometrically it is a well-defined Euclidean line of points all equidistant to a centre, to calculate its radius or area, the irrational number Pi is needed, introducing the idea of indefiniteness to a definite figure. The circle is also the shape of the wheel, a key feature in all machinery. The circle is a celebration of both technical and spiritual human knowledge.
Horizontal lines can represent the horizon, but also time, showing the beginning of things and running to eternity. Vertical lines can express movement up or down. Crossed lines can mark a unique place, or a confluence. A perpendicular intersection of two lines becomes a cross, a symbol of god in many religions.
The dot is the origin of all signs. Being both infinite and finite, it is ambiguous. As an infinitely small point, it is also marks an infinite dimension. In punctuation, it is the finite point of a sentence, marking the close of a concept. A dot cloud is an undefined number of dots that together form a vague shape, which is used in 3D software to approximate real, three-dimensional complex geometries. Dot clouds given an open definition of what cannot be clearly defined. They capture the essence of things.
The triangle is an ancient symbol of the godhead and the Trinity in Christianity. The rounded triangle is a triangle formed by the intersection of three arcs. Known geometrically as the Reuleaux triangle, it is the simplest curve of constant width other than the circle, which means it can rotate between two parallel lines touching its opposite edges. Its geometry is used in rotors such as in pumps and the Wenkel engine. Rounded triangles are symbols of constant energy.
