Theyyam is an ancient ritual worship that is still practiced in Malabar, the northern region of Kerala (southern part of India).
This one above is Kandakarnan, a spirit who eats dead bodies. The dancer's costumes are made from cloth and coconut leaves, with ornately designed, not to mention tall, headgear. The ring of fire completes the costume (goes to show how brave the dancer is - I imagine the costume is quite flammable).
