Viral Optical Illusion: Footprints in Sand Divide Viewers – Are They In or Out?

Melbourne, Australia – A recent social media post featuring an optical illusion of footprints in the sand has sparked widespread debate online. The video, uploaded by user @alicekjames, presents an image where viewers are divided on whether the footprints appear as indentations or as raised, three-dimensional forms. The creator explained that a friend sent her the photo, noting that half the people at a dinner party perceived the footprints as pressed into the sand, while the other half saw them coming out. She likened the phenomenon to the viral "white and gold versus blue and black dress" debate, which similarly divided public perception. Viewers are encouraged to observe the image closely, with some reporting that their perception switches between seeing imprints and raised forms, often after squinting or looking away. The post has garnered significant attention, with many users expressing their confusion and surprise at the visual trick.
