"Red Alien" was a multi-media art installation by Ommo Will* on display in Lennestadt, Germany earlier this year. The project told the story of an alien specimen recovered in the GDR, and eventually seized by the Soviets, sometime during the 50s. A huge number of props and faux documents were used to build the narrative, everything from ancient clay idols to the titular alien carcass. The Google translated version is over here.
