Reverse Reverse — Which Way Is It Turning?

Field notes

The experiment removes ordinary depth cues from rotating dot clouds, wires, and silhouettes so that opposite interpretations remain visually equivalent. Visitors can test six interventions, including blinking, shifting attention to a dot, changing the imagined viewpoint, and covering half the image. The technical notes specify orthographic projection and phase-based looping, while the page links the exercise to the kinetic depth effect and Pastukhov et al. 2012.
