Poster of Agamograph by Yaacov Agam

caption:
An agamograph is a seres of images that change at different angles. This style is named for Yaacov Agam. It is an art-style that involves movement and viewer participation; the viewer would see one image when the work was viewed from one angle and an entirely different image when the work was viewed from another angle. 

This is a cardboard poster of one of Yaacov Agam's agamograph; it does not appear as different images from different angles.
