Abstract
An image transformation puzzle comprising a series of elements with image portions on respective front faces thereof successively linked together for incremental translational and rotational movement around a closed loop path between different positions in which image portions of different elements combine to form different composite images. Image portions of successive elements combine in one of the different positions to reduce the total number of composite images in that position producing a vanishing image effect. The elements may be formed as solid profiles of the image portions.
