Attractive ceiling fans are hard to come by.  The one company I seem to always turn to for premier and contemporary options is the Modern Fan Company.  The Altus fan shown to the right is an attractive and sophisticated fan that works well in really any interior.  I have used these in previous projects and they seem to disappear in the room.  You don't want the fan to be the statement in the room, you want it to function well and blend in with your interior.  This is my best suggestion for a fan that meets both of these objectives.
