Biography Of Cool Desktop Wallpapers

The original Macintosh operating system only allowed a selection of 8×8-pixel binary-image tiled patterns; the ability to use small color patterns was added in System 5 in 1987.[6] MacOS 8 in 1997 was the first Macintosh version to include built-in support for using arbitrary images as desktop pictures, rather than small repeating patterns.

Windows 3.0 in 1990 was the first version of Microsoft Windows to come with support for wallpaper customization, and used the term "wallpaper" for this feature.[8] Although Windows 3.0 only came with 7 small patterns (2 black-and-white and 5 16-color), the user could supply other images in the BMP file format with up to 8-bit color (although the system was theoretically capable of handling 24-bit color images, it did so by dithering them to an 8-bit palette).[9] In the same year, third-party freeware was available for the Macintosh[10] and OS/2[11] to provide similar wallpaper features otherwise lacking in those systems. A wallpaper feature was added in a beta release of OS/2 2.0 in 1991.

There are also applications for changing automatically the Desktop Wallpaper like the Wallch, Desktop Drapes and Wally.

Similar functionality could be found in the Active Desktop feature of Windows 98 and later versions.

Wallpaper (also desktop picture and desktop background) is an image used as a background of a graphical user interface on a computer screen or mobile communications device. On a computer it is usually for the desktop, while for a mobile phone it is usually the background for the 'home' or 'idle' screen. Though most devices comes with a default picture, the user can usually change it to a file of their choosing.[1]
"Wallpaper" is the term used in Microsoft Windows before Windows Vista (where it is called the Desktop "Background"), while Mac OS X calls it a "desktop picture" (previously, the term desktop pattern was used to refer to a small pattern that was repeated to fill the screen).

The first version of Enlightenment was released by Rasterman (Carsten Haitzler) in 1997.[1]
Enlightenment has been under development for over a decade; its latest stable release is version E16 1.0.10.
Version 0.17, also referred to as DR17 or E17, has been in development since December 2000.[2] It is a complete rewrite on DR16 and was designed to be a full-fledged desktop shell, based on the new Enlightenment Foundation Libraries (EFL).

Biography Of Cool Apple

The Apple II series (trademarked with square brackets as "Apple ][") is a set of 8-bit home computers, one of the first highly successful mass-produced microcomputer products,[1] designed primarily by Steve Wozniak, manufactured by Apple Computer (now Apple Inc.) and introduced in 1977 with the original Apple II. In terms of ease of use, features and expandability the Apple II was a major technological advancement over its predecessor, the Apple I, a limited-production bare circuit board computer for electronics hobbyists that pioneered many features that made the Apple II a commercial success. Introduced at the West Coast Computer Faire in 1977, the Apple II was among the first successful personal computers; it launched the Apple company into a successful business (and allowed several related companies to start). Throughout the years, a number of models were sold, with the most popular model remaining relatively little changed into the 1990s. By the end of production in 1993, somewhere between five and six million Apple II series computers (including about 1.25 million Apple IIGS models) had been produced

The Apple II became one of several recognizable and successful computers during the 1980s and early 1990s, although this was mainly limited to the USA. It was aggressively marketed through volume discounts and manufacturing arrangements to educational institutions which made it the first computer in widespread use in American secondary schools. The effort to develop educational and business software for the Apple II, including the 1979 release of the popular VisiCalc spreadsheet, made the computer especially popular with business users and families.

The original Apple II operating system was contained in ROM along with Integer BASIC. Programs were entered, then saved and loaded on cassette tape. When the Disk II was implemented in 1978 by Steve Wozniak, a Disk Operating System or DOS was commissioned. The final and most popular version of this software was Apple DOS 3.3. Some commercial Apple II software booted directly and did not use standard DOS formats. This discouraged the copying or modifying of the software on the disks and improved loading speed. Apple DOS was superseded by ProDOS, which supported a hierarchical filesystem and larger storage devices. With an optional third-party Z80-based expansion card[6] the Apple II could boot into the CP/M operating system and run WordStar, dBase II, and other CP/M software. At the height of its evolution, towards the late 1980s, the platform had the graphical look of a hybrid of the Apple II and Macintosh with the introduction of the Apple IIGS. By 1992, the platform had 16-bit processing capabilities, a mouse-driven Graphical User Interface, and graphics and sound capabilities far beyond the original.

Despite the introduction of the Motorola 68000-based Apple Lisa system in 1983, and its more successful cousin the Macintosh in 1984, the relatively unsophisticated Apple II series was Apple's primary revenue source for most of the following decade. At its peak, it was a billion-dollar-a-year industry with its associated community of third-party developers and retailers. The Apple IIGS was sold until the end of 1992; the last II-series Apple in production, the IIe, was discontinued on October 15, 1993.

Biography Of Tom Cruise

Thomas Cruise Mapother IV ( /ˈtɒməs ˈkruːz ˈmeɪpɒθər/; born July 3, 1962), known as Tom Cruise, is an American film actor and producer. He has been nominated for three Academy Awards and has won three Golden Globe Awards. Cruise's first appearance in a major film was in 1981's Taps. His first leading role was in the film Risky Business,[1] released in August 1983. Cruise played the role of a heroic naval pilot in the popular and successful 1986 film Top Gun, and also secret agent Ethan Hunt in the series of Mission: Impossible action films.

He has starred in a variety of other successful films such as Rain Man (1988), Days of Thunder (1990), A Few Good Men (1992), Jerry Maguire (1996), Magnolia (1999), Vanilla Sky (2001), Minority Report (2002), The Last Samurai (2003), Collateral (2004) and War of the Worlds (2005). Since 2005, Cruise and Paula Wagner have been in charge of the United Artists film studio,[2] with Cruise as producer and star and Wagner as the chief executive. Cruise is also known for his support of and adherence to the Church of Scientology

Cruise's family spent part of his childhood in Canada, and Cruise attended Robert Hopkins Public School in Ottawa, Ontario, for grades three, four, and five. The Mapother family then moved to the suburb of Beacon Hill, so Cruise's father could take a position as a defense consultant with the Canadian Armed Forces. There, Cruise completed grade six at Henry Munro Middle School, part of the Carleton Board of Education,[12] where he was active in athletics, playing floor hockey almost every night, showing himself to be a ruthless player, and eventually chipping his front tooth. In the game British bulldogs, he then lost his newly capped tooth and hurt his knee.[13] Henry Munro was also where Cruise became involved in drama, under the tutelage of George Steinburg.[14] The first play he participated in was called IT, in which Cruise won the co-lead with Michael de Waal, one playing "Evil", the other playing "Good". The play met much acclaim, and toured with five other classmates to various schools around the Ottawa area, even being filmed at the local Ottawa TV station.[15] Cruise was bullied regularly in the 15 different schools he attended in 12 years.[11] When Cruise was twelve, his mother left his father, taking Cruise and his sister Lee Anne with her.[11]

He briefly attended a Franciscan seminary in Cincinnati (on a church scholarship) and aspired to become a Catholic priest.[16] In his senior year, he played football for the varsity team as a linebacker, but he was cut from the squad after getting caught drinking beer before a game.

Biography Of 3d Cool Wallpaper

An autostereogram is a single-image stereogram (SIS), designed to create the visual illusion of a three-dimensional (3D) scene from a two-dimensional image in the human brain. In order to perceive 3D shapes in these autostereograms, the brain must overcome the normally automatic coordination between focusing and vergence.

The simplest type of autostereogram consists of horizontally repeating patterns and is known as a wallpaper autostereogram. When viewed with proper vergence, the repeating patterns appear to float above or below the background. The Magic Eye books feature another type of autostereogram called a random dot autostereogram. One such autostereogram is illustrated above right. In this type of autostereogram, every pixel in the image is computed from a pattern strip and a depth map. Usually, a hidden 3D scene emerges when the image is viewed with the correct vergence.

Autostereograms are similar to normal stereograms except they are viewed without a stereoscope. A stereoscope presents 2D images of the same object from slightly different angles to the left eye and the right eye, allowing the brain to reconstruct the original object via binocular disparity. With an autostereogram, the brain receives repeating 2D patterns from both eyes, but fails to correctly match them. It pairs two adjacent patterns into a virtual object based on wrong parallax angles, thus placing the virtual object at a depth different from that of the autostereogram image.

There are two ways an autostereogram can be viewed: wall-eyed and cross-eyed.[1] Most autostereograms
(including those in this article) are designed to be viewed in only one way, which is usually wall-eyed. Wall-eyed viewing requires that the two eyes adopt a relatively parallel angle, while cross-eyed viewing requires a relatively convergent angle.

In 1838, the British scientist Charles Wheatstone published an explanation of stereopsis (binocular depth perception) arising from differences in the horizontal positions of images in the two eyes. He supported his explanation by showing pictures with such horizontal differences, stereograms, separately to the left and right eyes through a stereoscope he invented based on mirrors. When people looked at these flat, two-dimensional pictures, they experienced the illusion of three-dimensional depth.

Between 1849 and 1850, David Brewster, a Scottish scientist, improved the Wheatstone stereoscope by using lenses instead of mirrors, thus reducing the size of the device.
Brewster also discovered the "wallpaper effect". He noticed that staring at repeated patterns in wallpapers could trick the brain into matching pairs of them as coming from the same virtual object on a virtual plane behind the walls. This is the basis of wallpaper-style "autostereograms" (also known as single-image stereograms

Biography Of Cool Wallpapers For Desktop

Wallpaper, using the printmaking technique of woodcut, gained popularity in Renaissance Europe amongst the emerging gentry. The elite of society were accustomed to hanging large tapestries on the walls of their homes, a tradition from the Middle Ages. These tapestries added color to the room as well as providing an insulating layer between the stone walls and the room, thus retaining heat in the room. However, tapestries were extremely expensive and so only the very rich could afford them. Less well-off members of the elite, unable to buy tapestries due either to prices or wars preventing international trade, turned to wallpaper to brighten up their rooms.

Early wallpaper featured scenes similar to those depicted on tapestries, and large sheets of the paper were sometimes hung loose on the walls, in the style of tapestries, and sometimes pasted as today. Prints were very often pasted to walls, instead of being framed and hung, and the largest sizes of prints, which came in several sheets, were probably mainly intended to be pasted to walls. Some important artists made such pieces, notably Albrecht Dürer, who worked on both large picture prints and also ornament prints intended for wall-hanging. The largest picture print was The Triumphal Arch commissioned by the Holy Roman Emperor Maximilian I and completed in 1515. This measured a colossal 3.57 by 2.95 metres, made up of 192 sheets, and was printed in a first edition of 700 copies, intended to be hung in palaces and, in particular, town halls, after hand-coloring.

Very few samples of the earliest repeating pattern wallpapers survive, but there are a large number of old master prints, often in engraving of repeating or repeatable decorative patterns. These are called ornament prints and were intended as models for wallpaper makers, among other uses.
England and France were leaders in European wallpaper manufacturing. Among the earliest known samples is one found on a wall from England and is printed on the back of a London proclamation of 1509. It became very popular in England following Henry VIII's excommunication from the Catholic Church - English aristocrats had always imported tapestries from Flanders and Arras, but Henry VIII's split with the Catholic Church had resulted in a fall in trade with Europe. Without any tapestry manufacturers in England, English gentry and aristocracy alike turned to wallpaper.

During the Protectorate under Oliver Cromwell, the manufacture of wallpaper, seen as a frivolous item by the Puritan government, was halted. Following the Restoration of Charles II, wealthy people across England began demanding wallpaper again - Cromwell's regime had imposed a boring culture on people, and following his death, wealthy people began purchasing comfortable domestic items which had been banned under the Puritan state. In 1712, during the reign of Queen Anne, a wallpaper tax was introduced which was not abolished until 1836. By the mid-eighteenth century, Britain was the leading wallpaper manufacturer in Europe, exporting vast quantities to Europe in addition to selling on the middle-class British market. However this trade was seriously disrupted in 1755 by the Seven Years War and later the Napoleonic Wars, and by a heavy level of duty on imports to France.

In 1748 the English ambassador to Paris decorated his salon with blue flock wallpaper, which then became very fashionable there. In the 1760s the French manufacturer Jean-Baptiste Réveillon hired designers working in silk and tapestry to produce some of the most subtle and luxurious wallpaper ever made. His sky blue wallpaper with fleurs-de-lys was used in 1783 on the first balloons by the Montgolfier brothers. The landscape painter Jean-Baptiste Pillement discovered in 1763 a method to use fast colours. Towards the end of the century the fashion for scenic wallpaper revived in both England and France, leading to some enormous panoramas, like the 1804 20 strip wide Panorama, designed by the artist Jean-Gabriel Charvet for the French Manufacture Joseph Dufour et Cie showing the Voyages of Captain Cook. One of this famous so called "papier peint" wallpaper is still in situ in Ham House, Peabody Massachusetts. Beside Joseph Dufour et Cie other French manufacturers of panoramic scenic and trompe l'œil wallpapers, Zuber et Cie and Arthur et Robert exported their product across Europe and North America. Zuber et Cie's c. 1834 design Views of North America is installed in the Diplomatic Reception Room of the White House. Like most of eighteenth century wallpapers, this was designed to be hung above a dado.
