“There is the theory of the moebius. A twist in the fabric of space where time becomes a loop, from which there is no escape. When we reach that point, whatever happened will happen again.”
-Lieutenant Commander Worf, Star Trek: TNG, “Time Squared”

This science fiction theory plays out in this wonderfully unusual scarf! 

This very attractive black scraf has white details on the ends.  The moebius scarf is unique because it is connected and has a 180 degree twist.  This allows for the scarf to lie flat under coats.
