Hybrid images illusion: thumbnail images that turn out into a different image

Scientific American has a series of optical illusions including this one concerning hybrid images. The image from closeup looks like Einstein whereas from far it looks like Marilyn Monroe. Well I discovered that this same illusion holds if you shrink the image down to a small size. The smaller size image looks like Marilyn Monroe whereas the bigger size image looks like Einstein. The best way to see this version of the illusion is to take a picture of this on your phone. The thumbnail image on the phone will show up as Marilyn Monroe whereas when you open the image it will turn out to be Einstein. Pretty cool?
