Check out this livable art installation in Madrid. The piece is made from garbage washed up or dumped on European beaches. The trash has been sterilized and used to build a centrally located hotel with five double rooms. The rooms are free, but keep in mind there are no toilets or any other form of plumbing ;) Ha Schult, the artist, says, I created the Beach Garbage Hotel because the oceans of our planet are the biggest garbage dump."
