Don't say a word, just say thank you

I was lead to this by my friends at Knowledge is power. I like the ideal and want to see it spread.

The sign we are using is intended to communicate
"thank you from the bottom of my heart. "

To make the sign simply place your hand on your heart
as though you're saying the Pledge of Allegiance. Then
pull your hand down and out, bending at the elbow
(not the wrist), stopping for a moment at about the belly button with your hand flat, palm up, angled toward the person you're thanking.
