This tutorial teaches how to use masking in Adobe Flash by having the user import an image, place it on the stage, create a motion tween of a circle graphic moving across different locations on top of the image, and then applying a mask to the circle so that it reveals parts of the underlying image as it moves. The steps include importing an image, placing it on one layer and the circle on another layer, tweening the circle's motion across multiple frames, and finally applying a mask to the circle layer.
