Google Earth has a high resolution satellite photo of this past year's Burning Man event. Pretty cool. I found my camp and can even pick out my tent. I can tell from the position of the cars that it was Saturday afternoon at about 3-4pm, if memory serves, which it may not. Maps via Wikimapia, which is pretty cool too. Google Maps with comments.
I've you've got Google Earth installed you can use this placemark to see my tent. I'm actually sitting under the green parachute shade structure at the time this was taken.
Here's our camp. My tent is the small black square at the left side of the camp.
