"name": "The image features a white shelving unit with four compartments, each containing a distinct object. The top left compartment displays a figure in a dynamic pose, seemingly performing a dance or acrobatic move. The top right compartment holds a trumpet and an oscilloscope with a green waveform display. The bottom left compartment contains a vintage reel-to-reel tape recorder, while the bottom right compartment showcases a white bust and a skeleton in a seated position. The shelving unit is placed on a speckled floor, with a dimly lit archway in the background. The text \"KALLLAX ENTROPY CIRCUS\" is prominently displayed at the bottom of the image.",
