|1939 Papal Concave|
Business Insider called it a "Gorgeous Steampunk Contraption That The Vatican Uses To Announce The Next Pope."
The device that shoots the smoke up is this awesome, Jules Verne-looking stove. All of the paper ballots along with a chemical (to produce either black or white smoke) are placed in it and burned, alerting the world where the College of Cardinals is at in the voting.
Now you know that steampunk is achieving mainstream status.
Congratulations Pope Francis I.
I'll be watching you.
