ScentAir is a cool little Flash site. ScentAir has a cool little concept – bring custom scent experiences to retailers to help them sell more crap. I dig it. I want to have my shopping experience enhanced by the smell of gunpowder when buying my UZI. I’d also like that when I’m buying tobacco the store smells like, well, tobacco…but doesn’t it already? You know, that might work for all the KC Bars and Restaurants: pump in the smell of cigarettes to make you feel at home, but not the second hand ill effects…will we start finding second hand smell is killing us faster then cigarette smoke?
