Side-by-side photos of a very fluffy black dog. In the left image, the dog stands on a dark wood floor near furniture, its thick fur obscuring most of its body shape so it looks like a round puffball. In the right image, taken from above on a light-colored tile floor, the dog is curled into an almost perfect sphere of black fur with only one bright eye visible, enhancing the illusion that it is a fuzzy black eye ball.
