Free Download Wallpapers For Desktop Biography
PROPAGANDA is a large collection of GPL-licensed[1] seamless desktop backgrounds included in various Linux distributions, and available via free download over the web. While no longer being produced or even officially hosted online, the collection consisted of approximately 15 volumes of largely abstract and surreal art, numbering over 1,000 images in total. Created in GIMP by Bowie J. Poag, the images were meant to attract users to the platform by virtue of the art having been 100% Linux-generated.
The style of the images produced by Poag were unusual in terms of their geometric qualities. Appearing to repeat seamlessly along all four edges, PROPAGANDA images became attractive for use in 3D modeling, and particularly for use as desktop wallpaper, in that limitations in graphics hardware at the time often prevented users from using full screen 24-bit images. Using smaller, tileable images for desktop backgrounds helped keep memory utilization to a minimum, while still allowing early Linux desktops to be visually appealing.
After ten months, Poag turned control of the project over to Naru Sundar who was then a student at the California Institute of Technology. Although Sundar would subsequently release two additional volumes, Poag terminated the project in April 2000 citing a lack of activity by Sundar, and a falling out with Chris DiBona, a manager of community projects at VA Linux Systems, who provided hosting space for his project.
As a side source of amusement, PROPAGANDA's website featured a satirical storyline that John F. Kennedy had faked his own assassination in 1963, and had placed himself into cryogenic suspension until the time was right to lead the charge against Microsoft, and help the Linux movement gain footing. While not greatly influential, Poag's work with PROPAGANDA led many to develop an interest in Linux as a platform during its formative early years.[2]
The Propaganda site was formerly officially hosted at http://propaganda.system12.com/ and then http://propaganda.themes.org before going offline.
Airplanes Wallpapers have collection of desktop pictures from 640x480 and up to 1600x1200 pixels. An aircraft is any machine capable of atmospheric flight.
Aircraft fall into two broad categories:
Heavier than air aerodynes, including autogyros, helicopters and variants, and conventional fixed-wing aircraft: aeroplanes in Commonwealth English, airplanes in North American English.
Fixed-wing aircraft generally use an internal-combustion engine and propeller or jet engine to provide thrust, which moves the craft forward through the air. The movement of air over the airfoil produces lift, which allows the aircraft to fly. Exceptions are gliders which have no engines and gain their thrust from gravity and thermal currents. That is, in order to maintain their forward speed they must descend in relation to the air (but not necessarily in relation to the ground). Helicopters and autogyros use a spinning rotor (a rotary wing) to provide both lift and thrust. The abbreviation VTOL is applied to aircraft other than helicopters that can take off or land vertically. Similarly, STOL stands for Short Take Off and Landing.
Lighter than air aerostats: balloons and airships. Aerostats float in air in the same way that a ship floats in water, by displacing the air around the craft with a lighter gas (helium or hydrogen), or hot air. The distinction between a balloon and an airship is that an airship has some means of controlling forward motion and steering, while balloons simply drift with the wind.
