museum exhibit featuring an ornate astronomical instrument enclosed in a dark metal spherical cage. The cage sits on a highly polished dark wood platform with decorative columns at each corner. A small sign stands in front of the exhibit. A man in a white shirt sits nearby, looking at his phone. Another man, partially visible, stands behind him. The room is well-lit with white walls and a wood ceiling.
