Kitten / Dog Hybrid Image
Depending on your viewing distance, this hybrid image can be perceived in one of two different ways. When you look at the full-size image (see below), you will likely see a picture of a dog.
But if you move away from the screen, or squint your eyes, you will see a completely different image – a kitten. To make it easier for you, a smaller version of the image is provided below.
Hybrid images are a technique first published by Philippe Schyns & Aude Oliva (1994). This image was created with a free Android app called Face Mash which allows you to take photographs of two faces, merge them together, and create your own unique optical illusions.
