The raster bar (also referred to as rasterbar or copperbar) is an effect used in demos that displays animated bars of colour, usually horizontal, which additionally might extend into the border, a.k.a. the otherwise unalterable area (assuming no overscan) of the display. Raster bars, especially horizontal, were very common in demos for the Commodore 64, Commodore Amiga, Atari ST, ZX Spectrum and Amstrad CPC.

Famous quotes containing the word bar:
“Even the most incompetent English actor, coming on the stage briefly to announce the presence below of Lord and Lady Ditherege, gives forth a sound so soft and dulcet as almost to be a bar of music. But sometimes that is all there is. The words are lost in the graceful sweep of the notes.”
—Robert Benchley (1889–1945)
