A mezuza box by Israeli artist Yaacov Agam, who is known for contributions to optical and kinetic art. Images of geometric figures and the shape of the box form Magen Davids. The artist works with optical illusions. Becuase of the line composition and the features of the glass figures seems to be volumetric. Yaacov Agam is also famous for a type of print known as Agamograph, that uses barrier-grid animation to present totally different Images, depending on the angle from which the spectator is looking.
