All you need is love!

All you need is love!

The Gestalt Principles in this are pretty simple.  They are Proximity: the red arrows are all close together.  Similarity:  the arrows are exactly the same size, color, and shape. The only difference is that they are facing different directions.  The last element is closure:  these arrows are not actually touching, but the way they are placed allows our brains to see a heart shape. 

This is an advertisement that I saw in a magazine, and I first saw the "Continuation" principle.  The way the burgers are placed upwards, and the fact that the last burger isn't completed gives us the continuation principle, our eyes aren't focused on the first burger, but towards the top corner of the page, which is where the print is (if you look close enough, the only information on this advertisement is in the top left corner).  This ad also uses proximity and similarity because the burgers all look identical, and are all very close together.
