Micro-photography of a fly's eye - then a shot as a fly might see a child's toy - multiple images.
Story about flies.
C/U of a fly's head. "Flies can't turn their head - hence the all-seeing eye." Extreme C/U of fly's eyes. "Now for our micro-cine pictures." C/U of scientist putting something onto a glass slide to go under a microscope. C/U of the fly's eye - detached from the rest of the head. The eye is turned for the camera.
C/U of multiple lenses that make up the fly's eye. C/U of a camera lens. We then see a C/U of a child's mechanical toy seen through an ordinary cine-lens. Then the cine-lens is replaced with fifty from the fly's eye. We then see multiple images of the toy.
