Steampunk fans with a taste for horror will likely appreciate The Pyramid Gallery, which, besides being an online emporium where handmade “configurations” (as the puzzle boxes are known among afficionados) are sold, is a pretty remarkable piece of collective fan fiction. If you weren’t sufficiently in the know, it would be fairly easy to visit their site and imagine that it is, in fact, the online face of an obscure New York art gallery specializing in weird niche historical artifacts.
