Help me find an image fx

Some months ago i remember to see somewhere a nice image fx made (probably) using actionscript and maybe masks (i’m a total ignorant… :frowning:
Is a simple script where the image is showed drawing it from many vertical bars who become larger till the total show of the picture starting from the right to the left.
I don’t know if i’ve express it correctly.

Does anyone know where i can find something like that? there is somewhere a collection of image fx?.. the simple alpha fading start to annoying me…

important… i’m using Flash 5!
