I wrote about buying a 24 piece world jigsaw puzzle in this post from May -
Pop Culture and Synchronicity on the Road
I tried putting it together a while back, but got frustrated and put it away for later.
Today I found it in a drawer and decided I was going to put all of the 24 pieces together, which I eventually did.
24 hour time zone analogy, but the world is a far more complicated puzzle than any person on this planet can imagine, I think.
