the meaning behind the title of Braid?  Hope this isn't an obvious question..

The only things I can think of is James Braid, the "father of hypnosis", which would tie in to the game's theme of perception and subjection.
Or it could be a play on words-Considering string theory, Tim would be making a braid in the string of time :P.
 
 (To be honest I haven't played through the game but I have read much of the discussion about the end and want to buy it now!) 
 
p.s.-anyone notice how there is a 1 letter difference in Tim and Time?
