You’re a big fan of war movies and games, but actual war itself? Ick. Enjoy military authenticity while still keeping your limbs in the ballpark with these Grenade Oil Lamps from Piet Houtenbos ($59-$194). Custom-built from repurposed U.S. Army grenades, these lamps come in frag, smoke, or high-impact explosive varieties. The prices vary according to the finish, gold, silver, or natural. The reactions vary too, depending on whose feet you throw them at.
