One aspect of the invention provides scroll sign modules having laterally spaced-apart side frame members which support a pair of tape transport rolls therebetween. The axes of the rolls are parallel to each other. A tape, typically bearing visual indicia, extends between the two parallel rolls. A portion of the tape is wrapped around at least one of the rolls. Two controllable motors are mounted with at least a portion of each motor located in a bore of a corresponding one of the rolls. Each motor is operationally coupled to rotate its corresponding roll about its axis.
