black and white backgrounds for desktop

##title##
The desktop metaphor itself has been extended and stretched with various implementations, since access to features and usability of the computer are usually more important than maintaining the 'purity' of the metaphor. Hence we find trash cans on the desktop, as well as disks and network volumes (which can be thought of as filing cabinets—not something normally found on a desktop). Other features such as menu bars, task bars, or docks have no counterpart on a real-world desktop.

The desktop metaphor was first introduced by Alan Kay at Xerox PARC in 1970 and elaborated in a series of innovative software applications developed by PARC scientists throughout the ensuing decade. The first commercial computer that adopted this kind of interface was the Xerox Star.

One of the very first desktop-like interfaces on the market was a program called Magic Desk I built on a cartridge for the Commodore 64 home computer in 1983. A very primitive GUI presented a rough sketch of a desktop, complete with telephone, drawers, calculator, etc. The user made his choices by moving a sprite of a hand pointing with the use of a joystick and chose options by pushing the firebutton of the joystick. The Magic Desk program featured a typewriter machine graphically emulated complete with audio effects, calculator, organiser, and the files could be archived into the drawers of the desktop, right into their folders. A trashcan was also present.
