Phi Phenomenon
Ah Christmas, such a warm, family-oriented, wonderful time. And a time of visual illusion! One such visual illusion is the phi phenomenon in which lights next to each other blinking on and off in succession appear to actually move. For example, a string of lights across a house appear to “run” even though you know it’s just one light turning off and the one next to it turning on and so on down the line.
