so, who's going to man up and make a speaker out of limestone? :)also, i remember something like this and the whispering galleries in a mughal city. something used to warn of invaders of a city; you could clap in the middle of a tall dome and be heard from very far away, over 100m. anyone know what i'm talking about? i'll try and find the name of the city.
