Transhuman Space: Polyhymnia is a PDF adventure set in a unique nightclub. From the publisher's website:

At the dawn of the 22nd century, Polyhymnia is the coolest nightclub anywhere. In a world where entertainment fads rise and fall so fast that you can't even call them Flavors of the Month anymore, Polyhymnia has been around for more than a decade. It's never in the same place — or even the same experience — twice, thanks to the brilliance of Julian Cressida, one of the greatest memeticists ever.

But somebody has learned a devastating 15-year-old secret about Julian Cressida, and they need an independent group to get to the bottom of things... before Polyhymnia's true purpose is revealed.
