Attenzione, Attenzione!

How do we attract attention? Is there a principle? Obviously it's relative, for me it's human interaction. Oddity, alike profanity. Everything will excite someone, so how can you excite attention intuitionally? For humans it might be the smell, something similar to oneself. But how is it with materialistic things, places and art? Especially architecture, iconic buildings and places make people travel the world since Eva has yield to a temptation. Is it the recovery of home, our paradise? Or the unknown that keeps us moving?
