After seeing the new hat for the Angelica minifig from LEGO Pirates of the Caribbean line, I was curious to see if there were any custom creations of V from V for Vendetta. I was surprised to see that one of the best customs came from an unlikely source...Peter Reid (Legoloverman). You've probably seen Peter's highly 'greebled' Classic Space creations, but he's been known to dabble in minifigure customization from time to time.
You can check out the rest of Peter's creations on Flickr. Look for his two alien figure customs, they are not to be missed.
