The primal ornament (prototile) for my tessellations takes its origin from the Sumerian cuneiform signs.
The cuneiforms consist of wedges and hooks and reveal small resemblance with the ordinary tiles (polygons or other figures).
In the view of rotation, translation, and reflection, the signs can be joined by means of their overlapping parts, resulting in a continuous texture.
All tiles must be connected, isolated members are disqualified.
This form of tessellation with cuneiform signs allows to build various structures for artistic purpose.
The coloring may help with better recognition.
When the pattern is simple, there is no need in additional color
