#4: Burning Man
There are many things that are considered original to Burning Man, and the outlandish art installations are one of them. A surprising thing that not everyone knows about the festival is that the festival organizers do not pay for the artwork, it is all completely paid for by participants.
This incredible picture was from the 2018 Burning Man festival and started out much cleaner than the dusty mirrored ball you see here. Considering that in recent years the festival has been held in the Black Rock Desert, the artwork and the people are bound to get a little dusty.
