A method of forming round bottom corners for conductive lines in an integrated circuit is presented. At least part of the connecting member is movable relative to the proximal member to shorten the length of the connecting member located between the distal member and the proximal member and thereby retract laterally the sides of the wound opening. A shearing die assembly having a first aperture aligned with the feed channel is adapted to receive material and a second aperture is adapted to receive a ramming portion. Each non-linear compliant spring may include one or more routing segments. This provides for greater viewer attention to the advertising and for greater control by advertisers over the manner and length in which advertising is presented to viewers. The structure is light-weight and can be easily manufactured.
