I can't quite put my finger on it, but something about this Darth Vader wall clock just doesn't seem right. Actually, I just figured it out: It's the red eyes. It's as if Vader is evil, when we all know that despite his mistakes, there's still an element of good in him.
Every time you turn off the lights, the Vader wall clock will light up the eyes a fiery red and give you 10 seconds of heavy Sith breathing. It runs on three AAA batteries, costs $50 and is available now (although it did first appear on Giz back in September 2008...)
