At one group's camp was this camera
obscura, the first I've been able to see in person. Here's how they
work: a generally round-ish structure is built, and a small hole is drilled
in the side. Because of the size of the hole, as light passes through
it the view outside is projected upside down on the circle of walls inside.
While we were in this camera obscura, a water truck came by spraying down
the roads (to keep dust down). As is typical at Burning Man, the truck
was followed by a running naked fellow (in this case) trying to get cool.
Where are these photos from?: These
are photos I took at Burning
Man 2004 in Nevada (some photos were taken by Kevin too).
