There is no x without a y. These two friends have known each other for so long, they don’t leave the house without one another. Some say they even played together before z came around.
To celebrate their friendship, we created this decent yet wicked ceiling lamp. Two of our favourite illuminants have been attached to a raw steel tube that itself is suspended on a rope. Although flexible in tilt, our inner coordinate system allows for only one arrangement: when x meets y at the horizon.
