what is a screen saver?
A screensaver is a computer program that blanks the screen or fills it with moving images or patterns when the computer is not in use. Initially designed to prevent phosphor burn-in on CRT and plasma computer monitors, screensavers are now used primarily for entertainment, security or to display system status information.

A perfect screensaver must have the following characteristics:
  • A dark background or scene - This is to save power consumed by the display.
  • Moving objects or scene - This is to avoid pixel burning. Fixed objects must be dark.
  • Slow motion - The scene must be appeasing.
  • Silent - If you add sounds, use low-level ones and/or cool music.
  • Sensitive - It must stop on any user action (mouse move, click, keyboard hit).
