Stuart Anstis and Patrick Cavanagh: “The Squish Squash Illusion”. USA and Canada.
When an object is briefly flashed on or near a moving texture, it appears displaced. When the object is flashed on an expanding or contracting texture, it also appears to change shape, expanding or contracting with the background. These illusions come from a family of motion- induced position shifts where now the changes in perceived size and shape are much larger than any previous examples.
