I volunteered as a Greeter to the event this year, and got to get a sneak preview to explore and learn my way around. There are quite a few really awesome exhibits, although I am sorry to say that Burn2 is not there. We will be having a party on the Playa, too. Here are some pics.
I was very impressed with Ginger Lorakeet's exhibit of Immersive Photos, they will make some great backgrounds for fashion.
