"Universal Jigsaw Puzzle" Hits Stores In Japan 241

Riktov writes "I came across this at a Tokyo toy store last week, and it's one of the coolest things I've seen in a long time. Jigazo Puzzle is a jigsaw puzzle, but you can make anything with it. It has just 300 pieces which are all just varying shades of a single color, though a few have gradations across the piece; i.e., each piece is a generic pixel. Out of the box, you can make Mona Lisa, JFK, etc, arranging it according to symbols printed on the reverse side. But here's the amazing thing: take a photo (for example, of yourself) with a cell-phone, e-mail it to the company, and they will send you back a pattern that will recreate that photo. This article is in Japanese, but as they say, a few pictures are worth a million words. And 300 pixels are worth an infinite number of pictures."

      Not necessarily. There are 300! sequences of the pieces, but you also need to allow for a few more variables:
      • Rotation of pieces that are non-uniform in colour
      • Multiple arrangements - 15x20, 10x30, images etc.
      • Not using all the pieces - a 17x17 image for instance
      • Combining multiple sets of the same colour
      • Combining multiple sets of different colours

      OK, the last two are technically cheating, and all but the first option would possibly require custom code since all the example images appear to be 15x20 portraits, but a suitable algorithm probably wouldn't be that hard to figure out. I saw this on Firehose last night and worked out a few likely routines this morning, so I'd expect some custom FL/OSS code (and cheap Chinese manufactured knock-offs) to be available in fairly short order. After that the race will be on to create the largest most impressive image before the fad inevitably passes.

        Assuming all pieces are used, and that none of the pieces are symmetric or identical (that is, all pieces are different, and each rotation is different), then the actual number of possible images comes out to:

        9*(4^300)*(300!)

        where 9 is for the number of possible rectangles (1x300 up to 15x20), 4^300 accounts for the rotations of each piece, and 300! accounts for their arrangement.

        The result, according to Python, works out to around 1.143*10^796, which is large, but not infinite.

            If we still assume rectangular layouts, this is still not too hard to do. We simply sum d(n)*(4^n)*(n!)/2 for each n from 1 to 300, where d(n) is the number of divisors of n.

            Dividing by 2 eliminates the upside-down variant of each image, since we don't care about the orientation of the whole image (however, we do distinguish the horizontal and vertical orientations).

            The result of the full summation, again according to Python, is 1.1432*10^796, which, comparing with the previous result of 1.14299*10^796, is

      300! (factorial) ~= 3.06 x 10^614

      That's how many combinations there are, if each piece is unique and is used in the same 15x20 grid each time.

      To put that in perspective, there are only about 10^80 atoms in the universe. You would need 2042 bits to represent that number in binary.

      Impossible. Anyone who had seen the image would be a gibbering heap of insanity, and unable to tell you the pattern. At best you could hope to get enough clues to figure out the pattern yourself... but if you assembled it, you'd either off yourself or also turn into a quivering mass of human flesh.

      The key here is to get someone else to assemble the image... you'd find a likely mark (some kind of paranormal investigator, for instance) and then mislead him into thinking the image he's assembling will *stop* the summoning of Cthulhu. Drop enough clues in the right places, use decoys to mislead him of your true intentions, let him be an ignorant pawn in your great game. With luck and skill, you can get him to do the dirty work for you. And the irony of him contributing to the Great Awakening by striving against it is quite delicious.

        If the histogram is wider (higher variance) than your image, than they can "stretch" your picture out by upping the contrast. If it is narrower (less variance), than the noise approach is probably the best solution.

This would work best if the levels curve of your photo is not totally lopsided compared to the curve of the pieces.

      What makes this different from Legos, pixelblocks, ASCII art, or even a JPEG image, is that the selection of pixels/pieces is predetermined, limited, and they must all be used to make the image. For all those other forms you're allowed to pick the closest color value for each pixel.

    Q2. How do you do that?
    A. There are 300 pieces in the box with slightly different tones.A program finds the tones closest to those of your face and sends back to your cell phone a response image specially for your face.

    Q3. How quickly does the response image get sent back?
    A. It depends on the state of the communications network, but in about 10 seconds it should be sent back and then you can immediately start playing.
