The title of the series is a quotation of a fragment from Paul Valery1 cited by Walter Benjamin in the known "Work of Art..."2. The complete phrase follows.
"Just as water, gas, and electricity are brought into our houses from far off to satisfy our needs in response to a minimal effort, so we shall be supplied with visual or auditory images, which will appear and disappear at a simple movement of the hand, hardly more than a sign."
