Optical Movement Illusions

The core claim running through this archive is that static optical motion illusions are not motion-from-nothing. They are cases where asymmetric spatial structure and small temporal transients combine to drive otherwise standard motion computations. That makes them unusually useful both for mechanism work and for practical visual design.

I am interested here in both explanation and translation. The explanation side tracks luminance order, fixational instability, microsaccades, blinks, pupil dynamics, and cortical motion-network responses. The translation side asks how those same mechanisms can inform filters, image processing, and broader altered-perception design work without breaking contact with the literature.

Optical movement illusions are a good test case for a broader methodological issue in my work: how to talk about strange experience without mythologizing it. These images feel uncanny, but the literature also lets them be described very precisely in terms of temporal filtering, luminance asymmetry, motion detectors, and retinotopic processing.

That makes them ideal bridge objects. They connect hard mechanism questions to design questions about how one might deliberately build or soften motion, instability, or visual drift into an interface.
