I almost forgot to mention...today is the 100th anniversary of the Crossword Puzzle!
Here's a nice article on the history of the Crossword Puzzle from PuzzleNation.
And another article from PuzzleNation (great blog btw!) with an interview with David Kwong. He's a magician and puzzle constructor. The melding of the two is amazing! Watch the video and prepare to have your socks blown off!!
