title: Last but not least. Flashing lines.
abstract: In a periodic pattern of horizontally and vertically aligned quadrangles, two sets of illusory lines are seen to pulsate at orthogonal orientations, corresponding to the directions of knight's moves on a chessboard. The illusion seems to be governed by subtle rules of long-range interactions between parallel and non-parallel orientation filters.
