> Tetrahedron with four triangular faces and four vertices:
The tetrahedron is the simplest figure that stands for itself.
Composed from 4 triangles, the figure has led to search
the subtlety of three dimension the simplest way.
I stayed with the basic structure of the figure from the connections between the lines.
Observing the figure, to take minimum that it represents without to show it clearly ,
get it from respecting the connections of the 6 lines that make up the tetrahedron
to treat each of the lines in my aesthetic need to create a necklace.
