Spirograph is a geometric drawing device that produces mathematical roulette curves of the variety technically known as hypotrochoids and epitrochoids.The well-known toy version was developed by British engineer Denys Fisher and first sold in 1965.
Fretwork is an interlaced decorative design that is either carved in low relief on a solid background, or cut out with a fretsaw, coping saw, jigsaw or scroll saw. Most fretwork patterns are geometric in design. The materials most commonly used are wood and metal. [1] Fretwork is used to adorn furniture and musical instruments.

The meander is a fundamental design motif in regions far from a Hellenic orbit: labyrinthine meanders ("thunder" pattern [3]) appear in bands and as infill on Shang bronzes (c. 1600 BC – c. 1045 BC), and many traditional buildings in and around China still bear geometric designs almost identical to meanders.
Compasses are usually made of metal or plastic, and consist of two "legs" connected by a hinge which can be adjusted to allow changing of the radius of the circle drawn. . Typically one leg has a spike at its end for anchoring, and the other leg holds a drawing tool, such as a pencil, a short length of just pencil lead or sometimes a
If a geometric shape can be used as a prototile to create a tessellation, the shape is said to tessellate or to tile the plane. The Conway criterion is a sufficient, but not necessary, set of rules for deciding whether a given shape tiles the plane periodically without reflections: some tiles fail the criterion, but still tile the plane.

The scents of cinnamon and star anise add big flavors to this quick soup. Butter adds body and a silky texture. Fresh udon noodles take only a few minutes to cook, but dry udon noodles work well ...
[8] [9] Girih patterns can be created in woodwork in two different ways. In one, a wooden grille with polygons and stars is created; the holes can be left as they are, or filled with some material. In the other, called gereh-chini [10] small wooden panels of geometric shapes are created individually, and combined to create an elaborate design. [2]
