jigsaw puzzleA jigsaw puzzle is a tiling puzzle that requires the assembly of, often oddly shaped, interlocking and tessellating pieces. Each piece usually has a small part of a picture on it; when complete, a jigsaw puzzle produces a complete picture. In some cases more advanced types have appeared on the market, such as spherical jigsaws and puzzles showing optical illusions.Jigsaw puzzles were originally created by painting a picture on a flat, rectangular piece of wood, and then cutting that picture into small pieces with a jigsaw, hence the name. John Spilsbury, a London cartographer and engraver, is credited with commercializing jigsaw puzzles around 1760.[1] Jigsaw puzzles have since come to be made primarily of cardboard.Typical images found on jigsaw puzzles that also include scenes from nature, buildings, and repetitive designs. Castles and mountains are two traditional subjects. However, any kind of picture can be used to make a jigsaw puzzle; some companies offer to turn personal photographs into puzzles. Completed puzzles can also be attached to a backing with adhesive to be used as artwork.Knitting is a method by which yarn is manipulated to create a textile or fabric.Knitting creates multiple loops of yarn, called stitches, in a line or tube. Knitting has multiple active stitches on the needle at one time. Knitted fabric consists of a number of consecutive rows of interlocking loops. As each row progresses, a newly created loop is pulled through one or more loops from the prior row, placed on the gai ning needle, and the loops from the prior row are then pulled off the other needle.Knitting may be done by hand or by using a machine.Model building as a hobby involves the creation of models either from kits or from materials and components acquired by the builder.Categories of modelling include: Scale model building Live steam models Matchstick models Military models Model aircraft Model cars Model commercial vehicles Model construction vehicles Building modelsboard gameA board game is a game that involves counters or pieces moved or placed on a pre-marked surface or "board", according to a set of rules. Games can be based on pure strategy, chance (e.g. rolling dice), or a mixture of the two, and usually have a goal that a player aims to achieve. Early board games represented a battle between two armies, and most modern board games are still based on defeating opposing players in terms of counters, winning position, or accrual of points (often expressed as in-game currency). There are many varieties of board games. Their representation of real-life situations can range from having no inherent theme (e.g. checkers), to having a specific theme and narrative (e.g. Cluedo). Rules can range from the very simple (e.g. Tic-tac-toe), to those describing a game universe in great detail (e.g. Dungeons & Dragons) although most of the latter are role-playing games where the board is secondary to the game, serving to help visualize the game scenario.Scrapbooking Scrapbooking is a method for preserving personal and family history in the form of a scrapbook. Typical memorabilia include photographs, printed media, and artwork. Scrapbook albums are often decorated and frequently contain extensive journaling. Scrapbooking is a hobby commonly practiced in many parts of world. Karaoke is a form of interactive entertainment or video game in which an amateur singer sings along with recorded music (a music video) using a microphone and public address system. The music is typically a well-known popular song minus the lead vocal. Lyrics are usually displayed on a video screen, along with a moving symbol, changing color, or music video images, to guide the singer. In some countries[which?], a karaoke box is called a KTV. It is also a term used by recording engineers translated as "empty track" meaning there is no vocal track. The global karaoke market has been estimated to be worth nearly $1 billion. Photography is the science, art and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixe l, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.BIBLIOGRAFIAhttps://en.wikipedia.org/wiki
