A few days ago, a friend sent me this link with an amazing story about an artist called Tim Klein, who combines identically cut puzzles to make new images. Here are even more images on Tim Klein’s own page. The combined puzzles are for sale, although many are sold out. The train-horse is my favourite.
In the story above, Tim Klein credits Mel Andringa with the idea, and he was apparently the first artist to use this technique. Googling Mel Andringa brought up some more great images, like this:
I am definitely going to try this one day, but I think it might be much more difficult than you might imagine combining images in an entertaining way. Which is why these guys are artists, I guess 🙂
