He mails:"I finally managed to borrow a digital camera and a friendly photographer, and I am attaching a picture of the beautiful Zodiac Pentomino set y'all sent. Also pictured are a few of my other favorite puzzles: some are store-bought, some are home-made, and some were imported all the way from Belgium.
Thanks again for all the fun challenges and the wonderful things you have given me."
