The novelty of this magnetic Tangram is that it works with a third dimension and includes a new element: the need to strike a balance between the 7 pieces. The attraction between the tans (tangram pieces) is what ultimately sustains the figures and makes their handling so rewarding. As a result the upright figures can be seen and enjoyed from any perspective.
Tangram is no ordinary puzzle. The placement of the ‘tans’ and the observation of the figures come together to confer an aura of enigma and magic to the game, giving the Tangram its own special place in the world of puzzles and riddles. The possibilities that it provides for our imagination are virtually infinite. Much like when we put together a collage, the individual pieces of a Tangram lose their identity and appear before our eyes, magically, as part of a new form.
The puzzle is made up of seven flat, geometric pieces resulting from the dissection of a square. Each one of these pieces is called a ‘tan’ (part, in Chinese). There are 2 large triangles, 1 medium-sized triangle, 2 small triangles, a square and a rhomboid. How is it that the partition of a square in 7 parts – these 7 in particular – can yield such a vast array of fascinating, evocative figures? We have yet to come up with an answer, despite our search in specialized publications and web sites; perhaps the question would best be put to a mathematician.
It may be that the seemingly unsolvable nature of this question is itself part of the fascination that the puzzle holds over us. Or could the answer have something to do with the Chinese legend of the dragon Yu and the God of Thunder? The geometric shape of the square was, after all, of considerable importance in Chinese Antiquity, and a well – known Chinese proverb states that “Infinity is a square with no angles”.
The puzzle, whose popularity spread quickly throughout the Western world in the second half of the 19th century, had an impact on modern drawing as well. The ‘cubist’ nature of the figures helped to expand people’s visual habits, while the preponderance of a new triangular and cube-based drawing led to a renewed methodology of graphic construction. (The Tangram was also one of the sources of the 7th gift of Froebel’s program, which dealt with operations involving surfaces and planes). Its role in novel graphic approaches and methods would subsequently make the Tangram an important precursor of Western artistic vanguards in the late 19th and early 20th centuries such as cubism, vorticism and rayonism.
The puzzle has been used widely, especially in games and exercises involving spatial intuition. Its applications range from infant education to the advanced mathematical treatment of figures, partitions, metric geometry (area and perimeter problems) and Pythagorean and Euclidian mathematics. Archimedes himself (287 – 212 B.C.) came up with his own partition of the square in 14 pieces, each of which had a rational, knowable relation to the whole. He called it ‘Stomachin’ and used it to solve a variety of problems involving mathematical dissection.
As a puzzle, the Tangram can be played with individually or practiced competitively; with two or more Tangram, players can challenge each other to make different figures or to see who can make them fastest.
The 7 ‘tans’ can be used freely to create figures from our imaginations or to reproduce the given models, but in either case there are three basic rules: all 7 of the ‘tans’ must be used in the figure, they have to be in the same plane (in other words, they cannot be mounted on top of each other), and they must all be contiguous, having at least one point of contact with the rest of the pieces.
The 1600 figures compiled include a great variety of human and animal figures as well as objects and geometric shapes. We also find certain ‘paradoxes’, such as the way that two figures can be made that are identical except for one extra element – or a missing one – in one of the figures. For example, two human forms that are identical except for one missing foot, or that differ only in that one is holding something in its hand; or two squares that are the same except that one has a space in the center.
ORIGINS OF THE GAME.
Beyond the fact that it comes from China, little is known about the precise origins of the Tangram. The first written mention appears in a Chinese book from the year 1813. However, there is evidence from the year 1742 of a Japanese puzzle called “ch’ich’ae pan”, (puzzle of of the 7 pieces), a word dating from from the Chu era, which extended from 740 – 300 B.C. This has led a number of investigators to situate the origins of the game in this remote epoch. While the word Tangram was coined a little over a century ago by a North American, in Chinese the game has always been known as ‘the board of wisdom’ or ‘the board of the 7 elements’.
As a result of the Chinese publication from 1813 describing the puzzle, the popularity of the Tangram spread rapidly throughout Europe and North America, making it the Rubic’s Cube of its time. Numerous books were published depicting the figures that could be created. These were initially limited to the several hundred shapes described in Chinese books and texts, but new shapes and forms expanded the number to around 900. In 1973 the Dutch designers Joost Elffers and Michael Schuyt created, with a new, rustic version of the Tangram that they had conceived, 750 new figures, bringing the total number to over 1,600.
A Chinese legend related to the game makes reference to a fight between the God of Thunder and the dragon Yu that caused the sky to fall to the earth in 7 pieces. The pieces were so black that they absorbed all of the world’s light, thereby obliterating the forms of all of the objects on the face of the earth. The dragon, saddened by such a tragic happening, took the 7 pieces and set about constructing the different forms and beings that had existed, starting with the plants, animals and humans.
The novelty of this Tangram is that it works with a third dimension and includes a new element: the need to strike a balance between the ‘tans’. The attraction between the ‘tans’ is what ultimately sustains the figures and makes their handling so rewarding. As a result the upright figures can be seen and enjoyed from any perspective.

Our spine is the schematic representation of a tree trunk. Its function is that of sustaining and supporting, but its ultimate reason for being is to hold up its branches, which in turn carry leaves, blossoms and fruit.
Every object contains within itself its own archetype, a link to the time and the world to which it belonged. An old school desk can carry us back in time, evoking countless personal recollections while bringing to life the emotions associated with that particular period of our lives. In the same way, what is today the latest model of a cell phone will, with the passage of time, come to remind us of these days and of the world that created and used it. Objects serve to tell the story - and the history - of the people and the society in which they existed.
CÍRCULO is a game that involves a very simple mechanical force, pressure, but the results, always surprising, seem haphazard.
The circular ring is placed on a table, and different pieces will be put inside without any order or position. Then, the combination is pressed turning the screw. The pieces are moved by the pressure until they fit and the screw stops. When lifting the ring, it may happen that some parts fall down; those which remain inside will form figures that will surprise us.
A ESCADA is a ladder and a board. Together these elements come into balance, as can be seen in the suggestions images. Once the delicate balance between the ladder and the board is understood, it naturally becomes an open toy, allowing other elements to come into play and make it more complicated. There are no limits. We invite you to use any other object as a counterweight, for example: keys, a glass full of water, changing the board for a spoon or an egg, placing another ladder… these are just a few ideas. The interesting thing about the game is that each player can discover for himself the physical forces that serve to keep the ladder in balance.
