Special effects in the first flash bar to see the effect, but the original file seems very old, with flash2004 run will be wrong, personal norms inside of the AS, posted to everyone to see, perhaps useful

Slightly change the inside of the number, debug their own effect, the following picture is I do a screenshot of the Flash forum, inside the black cloud is dynamically generated
