Attention Sudoku lovers. If you believe that there's nothing more beautiful than a correctly filled Sudoku grid, with its unique columns, rows, and squares, then how much better is the same concept executed with nine unique images instead of numbers? The stationary company Objet de Carte has created greeting cards that fill Suduku grids — correctly solved, of course — with nine distinct images that share a similar theme. Their cards fit any occasion, from Christmas to Birthdays and Valentine's Day. You can even have a "monogrammed" set made using nine different fonts of your initial. The cards are beautiful, but we hope that soon you'll be able to frustrate your friends by giving them cards that are only partially solved.
