Screen savers
We all remember these fun "pipes" or similar screen savers that were appearing when computer is not used for a while. But what was real purpose of those animations?

Early on in the development of the personal computer, it was obvious that leaving a computer display up for viewing for prolonged periods caused a quicker deterioration of the screen resolution. Essentially, the constant display of the static combination and light and dark colors was creating problems with the way the screen would display colors. This effect was sometimes referred to as "burning."
In order to prevent this type of damage to the system, the idea of a motion driven display that would activate when a screen was left idle was developed. This moving display would allow the resolution to be constantly changing, thus preventing the creation of the burning effect and the resulting ghost images.
