Also also, for any of you who enjoy sudoku, the website visible on the picture is very highly recommended for hard puzzles - 5 of 'em every day. I keep printouts of the two hardest levels in my bag for commuting or occasions such as this. They trip me up regularly, which for my money is the mark of a truly good puzzle.
