WILHELM VEST for Vest. Austria. Ceiling lamp ‘Dymanic’. 1967. Lacquered metal, 15 rings. Measurements: 40 cm. diameter. Pendant lamp, model ‘Dynamic’ designed by Wilhelm Vest for the Austrian company Vest Leuchten in 1967. The design is exceptional in concept and quality. The circular metal rings in different colours are connected with ropes, and can be folded into each other when taken down. Nested in each other, they form a sphere whose colours range from the cool tones of a blue sky through the reds and oranges of dawn to the warmth of the sun at its zenith.
