So I’ve seen this masking trick from time to time and I’m trying to figure out how to do it. It is usually done when there is a banner and the pictures in the banner are revealed by what almost looks like a falling domino effect. It usually starts from the top left corner and then fills out to the bottom right corner. It’s revealed usually by what appears to be a bunch of small squares. Has anyone ever done this before? If so, can you give me a tute or some pointers? Thanks!
