Did you see Jeff's post about it on David's blog?  Nothing more than a "Thanks," but yeah.  How was it received in person?

David Belle sends his thanks to the parkour community as a whole. He was deeply appreciative of the picture, and he said it means a lot to him that so many people were willing to contribute. He's honored that we wanted to give something back to him, and he hopes we'll go on to do good in the world ourselves - as he is trying to do himself.
