Effects
To avoid attribute clash, static graphic displays had to be constructed with care. Finely-detailed color graphics were impossible, as color could only be applied in 8×8 pixel blocks. Careful design could achieve impressive results, as could synchronizing color changes to the refresh rate of the display — usually a television set.
However, animated displays were more difficult — a distinct drawback in a machine whose primary use was playing video games. If just one pixel in an 8×8 block was recolored because a moving part of the display touched it, the entire block would change color. Thus detailed moving graphics caused large ugly fringes of rapidly changing colors to follow them around.

Famous quotes containing the word effects:
“The machines that are first invented to perform any particular movement are always the most complex, and succeeding artists generally discover that, with fewer wheels, with fewer principles of motion, than had originally been employed, the same effects may be more easily produced. The first systems, in the same manner, are always the most complex.”
—Adam Smith (1723–1790)
“Some of the greatest and most lasting effects of genuine oratory have gone forth from secluded lecture desks into the hearts of quiet groups of students.”
—Woodrow Wilson (1856–1924)
“One of the effects of a safe and civilised life is an immense oversensitiveness which makes all the primary emotions somewhat disgusting. Generosity is as painful as meanness, gratitude as hateful as ingratitude.”
—George Orwell (1903–1950)
