The Phantom Wiggle

Best Illusion of the Year Contest - 2021 Peter Veto - “The Phantom Wiggle“ Country: Germany Author description: A flickering light source may sometimes appear dancing/wiggling when fixated. This is commonly observed in traffic scenarios. In a video demonstration, the phenomenon is simply caused by smear (or relative lack thereof) during individual frames. In real life, however, the possible causes are less obvious.
