Famous quotes containing the words optical and/or design:
“There is an optical illusion about every person we meet.”
—Ralph Waldo Emerson (1803–1882)
“The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
