Perception. 2006;35(11):1573-7. doi: 10.1068/p5668.

Abstract

A novel set of illusions that break brightness constancy and size constancy at the same time is reported. The illusions occur when observers move towards or away from these patterns. Many variations of these phenomena and a possible explanation are discussed.
