Last week, the Earth slid between the moon and sun, inciting a heady lunar eclipse that transformed our usual relationship with the sky. It’s almost cosmic timing for Manitoga, a stunning midcentury home turned design center that’s nestled between a granite quarry and a mossy slope in upstate New York. Just two days before the eclipse, the space’s doors opened for its latest exhibition, “Designing Nature” (through November 14). Fittingly, the first piece visitors encounter is the Eclipse Ceiling Lamp, designed by the contemporary Italian studio Formafantasma in 2016, which casts new, entrancing light on its surroundings.
