Few know the secret behind the giant, eyeless statues that stare blankly out across the ocean from Rapa Nui (or Easter Island, as it is more commonly known). Archaeologists have offered explanations ranging from religious to extraterrestrial. Recent ethnographic studies of today's Easter Islanders have uncovered a strong affinity for decorating the fronts of their homes with similar but smaller icons. Combining this research with core samples of the monuments themselves, experts have concluded that they were simply large-scale foam lawn ornaments. Lasting millenia longer than the lawns and the homes they decorated, the ancient figures of Easter Island are a testament to the durability of well-built foam art.
