The Mainz-Linez Illusion

This paper introduces the Mainz-Linez Illusion (MLI), a novel dynamic display in which rectilinearly moving targets appear to deviate from their true physical paths and instead give the impression of following the curves of static background elements. We attempt to relate the MLI to previously known effects and discuss possible mechanisms. We particularly focus on the possible role of negative afterimages, and speculate how their emergence and interaction with physical contours might contribute to some of the unique characteristics of the MLI. We also provide an online demo where readers can experience the effect and manipulate relevant parameters for themselves.
