Every so often I stumble on bits and pieces of memory from the only two times (thus far) that I've been to Burning Man. 2006 and 2007, specifically.
For example, this artist, who is apparently still doing large-scale installations all over the world: http://www.atlasobscura.com/places/the-passenger
I know of him through this structure, which I got to wander around inside during this particular Burning Man...and also got to watch it burn down, which was nothing short of awe-inspiring. http://arnequinze.com/en/projects/detail/uchronia
