It would seem that people are exploring the darker side of many things these days - not just fairy tales but folktales too. Santa's dark partner, who is all but forgotten these days, is creeping back onto the scene.
In the last couple of years art shows revolving around Krampus, short story collections including Krampus characters and Krampus art dolls have become more and more prolific.
As you can imagine, from the subject matter, there are quite a few disturbing images but I guess that's the point. While I think it's good to remember a dark side (especially to anything so "glitzed" and commercialized as the Christmas/Yule season) I'm not convinced going straight to horrific visuals for the most "demonic aspect" (and I'm not just talking about the Krampus-creature's appearance) is the way to go.
Here's another interesting piece from a showing earlier in the year:
You can see the details of the current show in the image at the head and, if you're interested, you can check out the variety of Krampus art on the website HERE. If you want to see it in person, the show runs in Chicago till January 15, 2012.
