Construx is a brand of building toys. These toys are made out of plastic. This brand was established by Fisher-Price in the year 1983. Construx generally has beam shaped pieces. These pieces have varying lengths. They can be snapped to a cubical connector to make large shapes. These shapes securely fit into each-other though no bolts or nuts are used. Flat surface assembly was possible due to panels. Even moving creations are possible in this set. You can fix many pieces and even wheels and motors and even hinges. This gives us the option to build a variety of new shapes and a variety of new working models. Sadly Construx was discontinued in 1988. Mattel tried to revive it in 1997 but his efforts were futile and it was again discontinued.

Parts of Construx

It has connector nuts of blue color of which all six sides could be snapped on to beams or other pieces. Wheels, toy figures, crane hooks, seats, engine panels, turntables, etc also are included in this set. Also provided are axles to hang pulleys and other pieces. These axels usually slide through connector nuts and also through the hollow of beams. Diagonal clips and flat plastic straps with hooks at the end to grab a nut are also included in this set of Construx. These diagonal clips can swing and thus give a momentum to the assembly. They are flexible and thus are perfect to reinforce corners. Many other separate and useful parts used to come with the set of Construx. It was a complete building set and very popular among children

The best way is to order it right away online or it can be purchased from many shopping outlet. It is available very commonly. Small children more than playing dominoes with rules enjoy using them as building blocks or something else to provoke their imaginations. Dominoes are available in many forms and sizes. They are mainly made of wood, clay, ceramic, heavy plastics, metals, etc. However they were originally made out of the carvings of animal bone or from ivory. Many prefer purchasing the ones made of wood or heavy plastics or substances that are more resistant. A domino is not restricted to one game but it can be played in many forms. A very interesting and famous way of playing it without any rules is by making them stand vertical in a line and then tripping the first one. It is fun watching the rest of them triple continuously. Many a times it takes a long time.

The company produced these sets from 1913 till 1967, but sadly it went bankrupt in 1967. Now-a-days the Erector sets that are being sold are basically ‘Meccano’ sets and are manufactured by S.N Meccano. This plant is based in France and is a part of the Nikko Group of Japan. But these sets are different than the original Erector sets and do not have the flanged beams. Nikko America is responsible for distribution of Erector sets in America since Jan 2006. Gilberto set has the honor to be the subject of the first ever national American toy advertising campaign. It was so popular that it is also the part of the American Folk culture. But its fame is declining now-a-days due to the availability of the new modern and more advanced toys.

It is a toy that produces a false impression of action from a fast sequence of still pictures. Slits are cut vertically in the sides of a cylinder. A set of individual images, drawings or pictures arranged in a sequence are placed on a band below the slits. The cylinder is then rotated and the viewer is supposed to look through a slit that is on the opposite side of the cylinder. The slits are scanned in order to keep the images from merging together and cause a blur image. Thus, the viewer sees a rapid sequence of images creating the fantasy of motion that is the same as motion picture or modern day “movies”. Usually images viewed through cylindrical zoetrope’s are thinner than their actual size.

Invention

This device was invented in 1834 and was referred to as “Daedalum”. It was invented by a person named ‘William Horner’. But before this a device similar to that of “Daedalum” was mentioned in the book ‘The Mysteries of Nature and Science’ authored by ‘John Bate’ in the year 1634. It is said that the earliest zoetrope was invented in China by the creative discoverer ‘Ting Huan’. He made this invention in 180 AD. In modern times the device was promoted by ‘William F Lincoln’. The “praxinoscope” was the advanced version of the zoetrope. The “praxinoscope” became poplar in the 19th century. There are different types of devices similar to the zoetrope and can create the same effect. Some of these devices are Electrochyscope, flip book this version is very common and very simple and is also used by small school going children, Phenakistscope, Strobe light, Tachometer and Thaumatrope.

Also called as building blocks or blocks or educational blocks, is one of the oldest and most famous toy ever. They are also considered as educational toys because they have got alphabets or numbers or animals drawn or printed on them. Children start playing with these blocks at a fairly early age of 4-5 yrs. Hence, these toy blocks are usually made of non-toxic materials like wood, foam, plastic. They are available in a variety of colors and shapes. They are usually very attractive and pretty in their appearance.

Brief History

This toy blocks concept originated in the 17th century in England. John Locke a philosopher made these blocks in 1693 and used them to teach children alphabets and made learning more enjoyable for them. Toy blocks have also been referred to as “rational toys” used to teach children spatial relationships which permitted them to see how different parts became a whole thing when added or joined together. These blocks were also helpful for teaching children about physics and gravity.

The first ever large scale production of these toy blocks started in 1820. This mass production was started in Brooklyn by S.L Hill. He also patented these toy blocks as “omamenting wood”. A writer named ‘Henry Cole’ and having the pseudonym of “Felix Summerly’ authored a chain of story books which had many references of toy blocks in them. These blocks were also used by many architects to make miniature or rough models of their buildings or other projects, all the further corrections and calculations were based on these models. Recently in the year 2003 these toy blocks were inducted as ABC blocks into the National Toy Hall Of Fame at the Strong Museum. This granted them the status of America’s toy of National Significance.

Overview

A Kaleidoscope is a tube of reflecting mirrors. It contains small objects like pebbles or beads or small pieces of colored glass. A person looks through one end while light enters through the other; the light gets reflected in the mirrors. Basically there are two mirrors which are set at 45 degrees to one another. Such an arrangement creates eight images of the same object. These images are a duplicate of each-other. At 60 degrees six images can be created, and at 90 degrees four images are obtained as the tube is rotated, round and round, this causes the light to reflect differently at each angle and thus causes many different patterns and colors which is very attractive and enjoyable to watch. Any unusual pattern or any distraught pattern also looks beautiful thanks to these mirrors and the reflections caused by them. A two mirror model is also available; its patterns are created against a black back-ground. While a model with three mirrors yields patterns that fill the entire back-ground. Any object or material is filled into the object cell. Many a times for more enjoyable viewing, object cells are even filled with water, this causes some extra special effects as the objects float on the water and cause a slight movement in respect to the viewer.

Working

In 2D symmetry kaleidoscopic a point is defined as the point of contact of two or more lines created by reflection symmetry. In general the lines form a ‘180 degree/n’ angle for an integer n > or = 2. This point is the center of n-fold rotational symmetry and ‘n’ number of lines, created due to reflection symmetry which can be present at this point.
