Forty-five and Ninety. 2 sizes, 2 angles, infinite possibilities. Clear candor of essential lines. The union of technique and art in a powerful solution made of pure volumes and minute details. Small alchemies of geometry. Unparalleled ability to evoke emotions with the apparent simplicity of the shapes. Forty-five and Ninety. 2 sizes. 2 angles. Only 2 orientations of lines in space manage in Roberto Garbugli's imagination to constitute an abacus of solutions that responds in an articulated manner to the most complex needs.
