On a playground, a young boy wearing a baseball cap with the word "FREE" on it stands in front of a red panel with a blue-rimmed, circular optical illusion display. The display features black and white concentric rings. A black knob protrudes from the center of the display. An adult in dark shoes and pants stands behind the red panel. In the background, there is a grassy area, a building, a bicycle, and a slide. The playground surface is red.
