Over the last few years the Call of Cthulhu fan site Yog-Sothoth has been running a series of recorded campaigns. Their latest effort is a run through "The Curse of Nineveh" from Cubicle 7. The adventure features a number of plot tokens that have to be collected by the players, among them a solid gold idol of Nabu Incarnate.
The statuette given to Neve Selcibuc by Archie Glossop, which in turn is given to the investigators at the start of this scenario, is known as “Nabu Incarnate.” It is approximately 20cm (8”) high and made from pure gold. The statuette is of a bearded king who appears to be transforming out of a second, plainer humanoid figure. The effect is to suggest some form of divine conversion or god-like birth. There are no marks or inscriptions save for a small sigil carved on the base, which looks like a rune of some kind: it is in no human language and requires a successful Cthulhu Mythos roll to decipher that it means “Yul’huthris”, a being with a link to the coterminous blasphemy that is Yog-Sothoth.
Wayne Peters was commissioned to create the idol based solely on that description. He's posted an in-depth look at the process from initial sketch to the final finishing of the 3-d printed piece. It's a fascinating process, and good look at the future of propmaking.
