At first glance it's just peas in a pod. But look closer, and you'll see that the entire thing is made of actual Ps...as in the letter P. How crazy is that? I just love stuff like this. (Side note, I think the technique is called 'stippling' - I remember doing some stippling in high school art. Check out that random knowledge!) Bonus for them, they have a P last name; so it works as a monogram as well.
