Machine à expresso art nouveau dans une fosse océanique profonde

An intricately designed Art Nouveau espresso machine, with flowing organic lines, submerged in a deep, crystal-clear ocean trench. Schools of exotic, phosphorescent fish swim around it, and ancient ruins dot the sandy floor. Moody, ethereal lighting creates a sense of mysterious underwater discovery, in the style of Alphonse Mucha and H.R. Giger, with a dramatic chiaroscuro lighting and vibrant, bioluminescent colors.
