Bitter Trolley by Bottega Ghianda pays homage to Victor Vasarely and his Op Art, with inlays that create optical illusions and subtle motion effects. This multifunctional piece features a maple wood frame with clean orthogonal lines and two horizontal trays inlaid with soft-toned leather. The top tray can also be carved from solid wood, forming a fish or leaf design. Even the leather wheels join the visual play, layered with contrasting slices of color.
