The first page of Professor Akiyoshi Kitaoka’s website says: “This page contains some works of ‘anomalous motion illusion’, which might make sensitive observers dizzy or sick.

Akiyoshi’s work in the Ritsumeikan University Department of Psychology plays with optical illusions of movement and color and does actually cause a bit of nausea.
