I don't know the name of the effect exactly, but it's at www.decor-rest.com , where the vertical rectangles slide back and forth along the image to "wipe" it.
Is there a tutorial for being able to generate those automatically and randomly, as opposed to one at a time? Ideally, one for someone who uses Flash at most once a year (i.e. beginner who has no intention of becoming advanced?)
Honestly I was laughing after I read your thread. Anyway I was interested in your question, you said you find it out, can you tell us how did you find it?
