<DIV>These puzzles offer more than just solving pleasure: they're also works of art! That's because every time you successfully complete a diagram, you also draw a picture. Along the top and left side of the grid are numbers that refer to the columns and rows: these are the keys to a code revealing which and how many squares to fill in. It just takes a little logic, concentration, and patience to figure it out?the process is a lot like sudoku, actually, where you work with numerical clues. But the result is something to show off, because out of the mix of black and white squares comes images of a bus, cat, pineapple, samurai, sphinx, and even James Dean!</div>
