Sign in to see author· 3h ago

Curated archive entry based on published research. Rows of offset dark and light tiles can make the horizontal mortar lines between them appear tilted, though they are parallel. This describes a documented perceptual effect under the cited conditions, not an independent personal report or evidence that the underlying physical measurements changed.
