display hack การใช้

• Display hacks have a history of several decades.
• Arguably the first display hack was a program called " Bouncing Ball " on the Whirlwind computer in the early 1950s.
• The Unix-based screensaver XScreenSaver collects the display effects of other Unix screensavers, which are termed " display hacks " in the " jargon file " tradition of US computer science academics.
• The "'Munching Square "'is a display hack dating back to the PDP-1 ( ca . 1962, reportedly discovered by Jackson Wright ), which employs a trivial computation ( repeatedly plotting the graph Y = X XOR T for successive values of T ) to produce an impressive display of moving and growing squares that devour the screen.
