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, users can usually change it to files of their choosing."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 X Window System was one of the earliest systems to include support for an arbitrary image as wallpaper via the xsetroot program, which at least as early as the X10R3 release in 1985 could tile the screen with any solid color or any binary-image X BitMap file.[2] In 1989, a free software program called xgifroot was released that allowed an arbitrary color GIF image to be used as wallpaper,[3] and in the same year the free xloadimage program was released which could display a variety of image formats (including color images in Sun Rasterfile format) as the desktop background.[4] Subsequently a number of programs were released that added wallpaper support for additional image formats and other features, such as the xpmroot program (released in 1993 as part of fvwm[5]) and the xv software (released in 1994).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.[12]A 'live wallpaper' is a type of application that works on a mobile device using the Android operating system. The application works as a wallpaper – providing the background image for the home screen—but also works as a conventional application since it can provide user-interaction with the touch screen (allowing the image to change dynamically, for example) and access other hardware and software features within the device (accelerometer, GPS, network access, etc.). Similar functionality could be found in the Active Desktop feature of Windows 98 and later versions. There is also third party software that provides this feature for various operating systems.

Gus Venditto, "Windows 3.0 brings icons, multitasking, and ends DOS's 640k program limit," PC Magazine (1 July 1990). There are so many customizable options, though, it's hard not to love the program. Even the background screen (which Microsoft calls "wallpaper") can be changed to display a custom design, so you can have your company logo on the opening screen with a .PCX file and a 5-minute change to the default settings.Charles Petzold, "Working with 24-bit color bitmaps for Windows," PC Magazine (10 September 1991). Every user gets seven device-independent bitmap (DIB) files with the retail package of Microsoft Windows. You can use these DIBs as wallpaper to decorate the Windows desktop. Five of the seven bitmaps have 4 bits per pixel to represent the 16 standard VGA colors. The other two are monochrome bitmaps that use 1 bit per pixel. Enterprising Windows users who frequent CompuServe can dig up some 8-bit (256-color) DIBs from the data libraries. Generally, these have been converted from existing files that were in the Compu-Serve Graphics Interchange Format (GIF). These 256-color DIBs are usable as wall-paper on the IBM 8514/A adapter and on those Super VGA boards that support 256 colors under Windows. Windows will use the colors in the DIB color table to set a palette for the wallpaper display. [...] If you think about it, though, the poor performance is entirely understandable. Windows or more precisely, the device driver for the video adapter must convert each 24-bit pixel into an 8-bit pixel-bit value that's an index into the system palette.Roger Gilbert, "33 unsung shareware programs", MacUser (1 October 1990). Are you envious of a colorful background picture on someone else's desktop? Start using ColorDesk, an advanced version of the INITs that allow illustrations to replace the background patterns.

Free Wallpaper For Computers Biography Betancourt was born in New Jersey in 1971. He attended Temple University in Philadelphia, PA to study motion pictures, and then received an MA in Film Studies at the University of Miami in Miami, FL studying under film historian William Rothman. He also received his Ph.D. from the University of Miami in Interdisciplinary Studies, focusing on Art History, Communications/Film Studies and History.
In addition to scholarly work, he has written popular articles and reviews on art, art theory and culture for the Miami Art Exchange [1] and Art Scene magazines.Betancourt has discovered that the inventor Mary Hallock-Greenewalt produced the earliest hand-painted films known to still exist.[1] However, these were not movies but films produced specifically to be performed by her earliest version of the Sarabet which was a machine for automatic accompaniment to records. This device was an early music visualizer of the type now included with computer audio-players. Even though these films were not designed to be motion pictures, they were produced with templates and aerosol sprays, producing repeating geometric patterns in the same way as the hand painted films of Len Lye from the 1930s.
He has also published a short monograph, combined with a large collection of short essays, pictures and other archival material about the visual music group Lumonics that was organized and run by Mel and Dorothy Tanner in South Florida.
Most of his other visual music-related scholarship takes the form of anthologies of technology patents, or reprints of earlier texts on visual music machines designed for live performance.

Betancourt's construction of formalism suggests a broader scope for applications of film theory than simply motion pictures since it focuses on both painting and experimental film. This approach was developed in his book, Structuring Time: notes on making movies. He approaches the motion picture as a series of distinct, but related domains of aesthetic manipulation: camera, image, editing, projection, screen, and sound.In a series of articles starting with "The Aura of the Digital," Betancourt has criticized what he called the “immaterialism” of digital technology, specifically the claims that digital technology ends scarcity through being able to create value without expenditure, unlike the reality of limited resources, time, expense. It is based on denying the actual costs of access, creation, production, and maintenance of computer networks and technologies. He sees the “aura of the digital” as both the capitalist fantasy of continuous expansion made possible by digital technology and as the anti-capitalism fantasy of a world without scarcity or need for capitalist production.[3]Betancourt’s concept of the “aura of information” is the separation made possible by digital technology of the information and the ways that information is carried by technology. This idea claims the digital transcends physical form by separating meaning from the physical objects that present the meaningful information to its audience. It is the tendency to ignore the particular physical details of how we encounter information, in favor of just paying attention to the information itself.[4]
