a.k.a. chip art -or- microchip graffiti -or- photomicrography
Very small images that have been placed on a microchip for fun by the engineer who constructed it. These images (such as Waldo, Daffy Duck, the engineer's signature, or a variety of slogans) are so small they can only be seen with a microscope (for example, three of them next to each other would equal the width of a hair).
