title: Phantom arcs: now you see them...
abstract: A new visual illusion is reported and illustrated. The illusion, dubbed 'phantom arcs', survives manipulations of contrast, scale, and hue. The arcs can be seen in printed versions as well as in images displayed on CRT or LCD monitors. Data collected in an undergraduate perception class reveal that the illusion can be seen by untrained observers.
