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."
