Indian gesture language for Merry Christmas, and is to be read "Sun shine in the heart a baby boy, Great Mystery, born on this day."
While looking for something on a completely different topic I ran across this page of hand gesture signals. Some of the pictures are quaint, others plain silly, but I found it interesting none the less.
Of course this got me interested in what documentation I might find on more modern gestures. This page offers quite an interesting take on some familiar gestures.
