Hope your editing process is going well - I just saw your post about the book. I'm at work and heading home to deal with building furniture at my new place in San Francisco, so I don't have time to go through them at the moment. I did, however, want to tell you that this particular image from Robot Heart is amazing and should be at the top of the heap for your book submissions:
I was super sad I couldn't make it to the burn this year, but that picture captured everything I love about the playa - the crowd, the time of day, the random smattering of art cars - it's awesome. I would be interested in buying a print if you ever get around to it.
