The Creative Prose newsletter this week (from creativepro.com) had links to some very entertaining time wasters:
Typeflakes -- make snowflakes with words and email them to your friends (this is my favorite)
Cake writing generator -- even if you've never been good at writing with icing
Dance writer -- a dancer makes letters as you type them
What chefs do when they're bored -- the title says it all
Have fun and Happy Thanksgiving!
