Burn 2 Carnival of Mirrors continues through the 25th. The photo above shows one of the many places to hang out and tell stories or whatever.
There’s a schedule of live music and other events. 
There’s quite a variety of things to see. Many of the installations have land descriptions such as the one for the space above that has a lot of watery mirrors and fire:
“Camp Envy Mirror ThisA CampEnvy Chillspace by a RL Nevada Burner. MirrorTheme, music-& Fire, & a some Tesla effect 2-Take a peek in2 this tentOmirrors& kick back-RL Guitar playing just may break out NEtime! Love2 discuss RL BurningMan & NEthing Nevada. Enjoy UR burn! )*(“
Who is that weird lady in the plague mask and Viking helmet?
“Paintings and sculptures and maybe a few freebies by a sl builder and rl amateur artist.”
The above photo shows a resting and snack place near the welcome entry. There are greeters and helpful people around if you have any questions.
I’ve met many Firefly fans in both Second Life and Opensim. The photo above is a Firefly Companions Guild.
Clicking on one of the framed photos connects you with a companion that will pour you some tea or some such.
But I was more in a mood for playing with the parachutes. 
The snapshot above was taken inside A Clam built for Organica by Jedda Zenovka. I happened to be there at the same time she was and she told me a bit about Organica, a psy music community, which sounds like a place worth checking out when I have more time. She mentioned discussions about sustainable living and the environment. I popped in to make sure the LM is accurate and found this in the land description:
