Welcome back to the default world. (Bummer, I know.) However, if you want to keep a little bit of the playa with you all year long I've got an art project you might be interested. This year at the burn I took a picture for every day of the year. They will be uploading at 12:01 on the corresponding day.
You can either just watch the flickr account directly (the set is here) or follow the livejournal rss feed at 365burningman. If you follow the RSS feed here on lj, clicking the picture will take you to flickr to see the picture in high resolution.
