Jessica TUT5: This is a nice use of Gestalt Principles too, we can see a hand hugging a man. We can also see that the hand belongs to a lady because of the details it shown, the nail polish for example. Through graphics, we can see a simple message from it. In my opinion, the picture is trying to tell us how protective the woman is to the man.
Continuation- This picture represents Gestalts principle of continuation. The eye flows along the curve and the image is seen as a whole picture that your eyes sail through, If there was a logo at the smaller end of the lines your eyes would flow right to that.
