#rykarn's optical illusions
Warning: Flashing imagery. Pressing the play button on the image below will cause a rapidly flashing animation to play.
An image of a landscape with an Eggbug overlaid. The landscape image and eggbug image are made to animate with a short, quick, movement. When the movement is completed, the colors of the image inverts and the motion restarts. This creates the illusion that Eggbug is always moving towards the viewer, yet it never actually changes position.
