1. An information-presentation (“

  • IP”

    ) structure comprising an object-impact (“

    OI”

    ) structure having an exposed surface for being impacted by an object during an activity, the OI structure comprising a variable-color (“

    VC”

    ) region which extends to the exposed surface at a surface zone and normally appears along it largely as a principal color during the activity, the VC region comprising an impact-sensitive (“

    IS”

    ) component and a color-change (“

    CC”

    ) component, wherein;

    an impact-dependent (“

    ID”

    ) segment of the IS component responds to the object impacting the surface zone at an ID object-contact (“

    OC”

    ) area spanning where the object contacts the surface zone by providing an impact effect if the impact meets threshold impact criteria; and

    the CC component comprises an electrode assembly comprising (a) near electrode structure, (b) far electrode structure situated generally opposite to, spaced apart from, and situated farther from the surface zone than the near electrode structure, and (c) a core layer situated at least partly between the electrode structures, light having at least a majority component of wavelength suitable for forming the principal color normally leaving the core layer along the near electrode structure for enabling the VC region to normally appear along the surface zone largely as the principal color, a CC control signal provided by the VC region in response to the impact effect, if provided, being applied between a location in the near electrode structure and a location in the far electrode structure, at least one of the locations dependent on where the object contacts the surface zone, an ID segment of the core layer responding to the control signal by enabling light having at least a majority component of wavelength suitable for forming color different from the principal color to temporarily leave the ID segment of the core layer along an ID segment of the near electrode structure such that an ID portion of the VC region temporarily appears along an ID print area of the surface zone largely as changed color materially different from the principal color, the print area at least partly encompassing, at least mostly outwardly conforming largely to, and being largely concentric with the OC area.
