What is the name of this?

Amma pointed at the ornate brass lamp in grandmother's photograph, her weathered fingers trembling. "What is the name of this?" she asked our family group, voice uncertain in the digital space. Within hours, responses flooded in from cousins scattered across continents. One from Srivilliputhur recognized it instantly—a traditional deepam, exactly like those lighting temples in our ancestral village. She shared stories of festival mornings, the oil seller's calls, smoke curling toward stone ceilings. A younger cousin posted restoration techniques. Another shared museum links. Their engagement meant something precious: Amma earned enough to buy supplies for the neighborhood children's Tamil classes. But the real reward glowed brighter than any algorithm's reward. Our heritage, suddenly alive again, bridging generations through her simple question.
