Not sure how many Firefly/Serenity fans have seen this, but there was a viral advertisement series that was leaked on the web over the last few months called the R. Tam Sessions. Won't make much sense to anyone who hasn't seen the series or the movie, but for fan's it's an interesting look at River's fall into psychosis. A fan site collected them and has them available for download, both in their original seperated format and spliced together as one reel. It's a little disturbing, but good stuff.
