Gestalt

Gestalt - A physical, psychological, or symbolic arrangement or pattern of parts so unified as a whole that its properties cannot be derived from a simple summation of its parts. May also refer to a school or theory in psychology known as Gestalt psychology.

Here is an animation of four pictures, each an arrangement of coloured squares of decreasing size, increasing number, and increasing complexity. As the animation progresses there is a moment at which the viewer identifies the image from which the images were derived. This experience might be described as achieving closure or making a new gestalt. This experience is also likely to arrive earlier in the sequence the more times one sees the animation. Even the final image is actually a greatly distorted reproduction of the original picture. See derived image, metamorphosis, and pixel.
