Beatmaps, an event listings mashup, just posted a neat Burning Man mashup. This tool combines Google satellite maps with Burning Man's schedule of events, a user-generated tagcloud, etc. Registered beatmaps users can add themselves, their camp/artwork/events, etc. and tag everything as they like. (Compare this to the official burning man calendar.) Ideally, this mashup is also sucking in data from existing sources, but it's hard to tell from the limited info at the beatmaps site, which is in beta.
