Knotology, the art of creating spheres from strips of paper. Projects The second project: A sphere of colored strips. Take 6 strips with a length of 12 times the with. In our example we will use 6 strips of 2cm x 24cm in the colors purple, blue, green, yellow, orange and red. Because of the fact that these strips also need diagonal folds, you can make witches ladders at a different way. We will make one witches ladder from one strip. Take 5 strips, leave the 6th. First we are going to make the "northpole". You will get 5 pyramids, with triangular bases, who will meet in one point. The 6th strip we call the equator. Mandala de Tsurus - Passo a Passo. Oi galera! Atendendo a pedidos estou postando um passo a passo da Mandala de Tsurus. É muuuito fácil de fazer!!! Só não reparem na qualidade das fotos, foram feitas hoje, sábado de manhãzinha, na cama e de pijama ainda rsrs Começa com a base da bomba d´água. Dobre as pontas para cima.
Origami - Folding Instructions. Re: Origami star (Five intersecting tetrahedra) Origami Geometric Constructions. This visually stunning object should be a familiar sight to those who frequent the landscapes of M.C. Escher or like to thumb through geometry textbooks. To construct an origami version it is essential to have a good understanding of the object's structure, which the accompanying pictures try to illustrate. To the right is shown a dodecahedron - the classic polyhedra with 12 equal sides. If we were to take 4 equidistant corners of the dodecahedron and connect them with lines, the result would be a pyramid (a tetrahedron) inscribed in the dodecahedron. This is illustrated below. This tetrahedron has 4 corners, and the dodecahedron has 20 corners total.
Thus the left hand picture illustrates what five intersecting tetrahedra look like, and notice how all these pyramids are cutting into each other. So here is the task: Given this wildly complex-looking structure, how do we make it out of modular origami units? And what do ya know? Francis Ow's 60 degree Unit OK! How to interlock the units. How to make Enrica's Dodecahedron Kusudama Tomoko Fuse's Espiral (Spiral) BOS academic : Curler Units by Herman Van Goubergen. Curler Units Use small squares (max 7x7 cm) of stiff paper.
Ordinary origami paper is too thin, but photocopy paper works very well. Make a waterbomb base and curl each of the flaps into a cone. As shown in the top view, all flaps are curled clockwise (left-handed folders may find it easier to work from a mirror image of these diagrams - sorry!) The paper should stay curled up as indicated (that's why you need heavier paper) so initially you'll need roll up the flaps a bit tighter than shown in the drawings as the curls will open out slightly when you let go. To assemble the units, gently ease one curl inside another curl. The final drawing (below) shows a cuboctahedron.
Continue building the cuboctahedron until you run out of units. Surrounded by 3 squares. If this explanation doesn't work for you, try the diagrams at the right. Further experiments : To make an icosidodecahedron (which consists of 3-vortexes and 5-vortexes) you'll need 30 units. Herman Van Goubergen. ORIGAMI MODULAR en Argentina - Laura Azcoaga.
