Many people love to work with jigsaw puzzles. I'm not really one of them, but I happened upon Jigsaw Planet, a well-designed site for making online jigsaw puzzles out of any of your photos. You can then sent the URL of your puzzle by email to anyone. The graphics are clever and the entire system is easy to use. Check out this puzzle of my mother-in-law's beautifully weathered piano keys, for instance. Note: This post earlier linked to a site called "Jigcool." I took down the links to JigCool after seeing Mindy's comment. I went back and visited the site and I was shocked at the explicitly pornographic ads that accompanied what seemed to be a site meant for kids. These are not the types of ads I saw last night when I tried out the site. This is truly bizarre. I've replaced the link in this post to a different puzzle site that does not have any advertisements.
