"Recently designers took inspiration from an American art-form, the mobile, a sort of space-time genealogical tree which balances a family of balls, bars and melon-slices on a series of delicately interdependent arms. Today there is a growing obsession with the unrehearsed, the totally spontaneous. The expedient of blindfold drawing is producing marks, stains, smudges and other assaults on the paper. The designer with this indubitably free hand claims it is as much a part of nature as the glide of a snake or the track of wet pramwheels, and that being in this sense style-free it can never date."
