I like pointing. Pointing identifies objects, chooses one thing over another, and implies a direction. That's why I started pointing at planes.
You don't even need a hand to point - photographing something is a way of pointing at it. And aren't planes already pointing?
Arrows are icons that describe pointing. An arrow assigns importance to anything at its sharp end. But an arrows, traditionally, is a weapon - and anything at the end of it a victim.
I'm always looking for new ways to point, and new things to point at.
