‘The Truffle’ was hollowed by a cow

The project involved pouring concrete over hay bales stacked and burried inside soil from the surroundings. Once hardened, the resulting shape was exhumed and sliced open. A cow (named Paulina) was then allowed to eat away the remaining hay bales to reveal the interior space over the course of a year. You can watch a movie documenting Paulina’s great job here and a making-of at the end of this post.
