Abstract
Playground apparatus including a plurality of conventional playground swings which are supported for oscillatory or reciprocating movement above a ground surface by swing support structure. The apparatus further includes a target object which may be an inflated or air-filled spherical ball pendulously supported above the ground surface. The swings may be disposed so that the normal paths of their travel converge toward the target object so that participants using the swing may attempt to contact the target object as a play activity. Alternative target objects and swing configurations are disclosed.
