A couple of silly puzzles to kill time with...

• Hide'n'seek (find book titles)
• Crossword puzzle (Java applet)

Don't know if this is *fun* as such, but I do like languages...

• Kingopedia — book titles in different languages
  There're now titles in: English (duh), Finnish, German, French , Czech, Italian, Swedish, Danish, Norwegian, and Dutch. They're missing a few. If you have or you know a non-English Stephen King site with bibliography, do let me know.
