This past weekend was the annual lantern festival in Seoul.  I am not 100% sure, but I think it is held each year to honor the god of lanterns and ensure a full and robust lantern crop.  The legend is that one year the festival was not held and the entirety of Korea remained dark for a century as a punishment from an angered and vengeful lantern god.

The culmination of the festival is a parade in which over 100 million lanterns stream past the crowded streets, held aloft by the cities children, monks, and wizards.  Also there are two giant neon fire breathing dreams. They represent the eternal struggle of night and day for dominion over the earth.*

*Disclaimer: I was only at the festival for 45 minutes and have no idea why it was held or what really happened before or after I left.  I apologize.
