The jukebox itself would feature a convincing set of heart and lungs sitting in a bell jar, that would pulsate, inflate and deflate in sync with each heart beat and breathing cycle.

Make sure that there is broad spectrum of humanity represented: from the great and the good to the destitute and the dastardly; from presidents to terrorists; the saintly and the psychopath.

Let all be carefully recorded and lodged on the Cardiac Jukebox. Pop in a coin and watch as the jukebox makes a random selection for you, displays their photograph togther with a brief resumé of their life to date.

Sit back as your ears are filled with the subtle beating of a famous heart, and the sound of breathing, just as you would hear it if your ear was pressed against their chest.
