Christopher Walken in Space!
Christopher Walken appears to be flying through space. However this is an illusion.
The picture is an animated GIF, and it contains 4 discrete pictures. The first 2 are normal black and white, although slightly shifted in respect to each other. The second 2 are inverted images (i.e. the negative version) and again the 2 images are slightly shifted in respect to each other. When viewed as a sequence, however, Christopher Walken appears to be moving through space - in 1 direction continuously!
