Sudoku Whiteboard

Here's a great little idea for those times when your eyes have gotten tired of quinting at a little 3" x 3" grid, or worse still, at the computer screen (or even worse still again, at your PDA screen!)...

Simply draw up a Sudoku grid using permanent markers on a whiteboard, then write in numbers to your heart's content with a standard whiteboard marker.

Possibly a good idea to put up in the coffee area at work - a bit of communal Sudoku - although maybe the boss would get a bit concerned about the length of coffee breaks!...

Enjoy, Tim.
