Looking for unusual electrical component

I'm looking for something that can be used as a passive (unpowered) shaft encoder which also provides direction of rotation. I can envision two types of devices. One would be a potentiometer that would sweep through some resistance (0 to 10k for argument sake) in a single revolution (360 deg) then would start all over once you turned past 360 deg. In other words I need an infinite turn pot that repeats the resistance taper with each revolution. An alternate configuration would be an infinite turn pot that had say 120 or more discrete resistances per rev. Any ideas where I get a FIRST legal device as described? How about ideas for making one?

Thanks,

James Jones
