Mole-Balls is an interactive sculpture game built around the concept of Whack-A-Mole. Two teams. One team attacks by throwing rocks, knifes or grenades at the other team, the Moles. The moles, are represented by human beings from the other team wearing a mole-face bicycle helmet. The moles job is none other than to stick their heads through an array of painted boards with holes cut out of them, and hold still, so the other team could inflict mortal damage.
