Scented

Instead of tagging a wall with paint, Mitchell Heinrich tags it with a scent. There is now the potential to make a subway platform smell like freshly cut grass. Since the scents are not permanent; they eventually evaporate leaving no trace.

"Scent is interpreted by the limbic system which is very closely tied to emotion and memory. This leads me to believe that interacting with people using scent can potentially be a much more powerful medium than paint since people experiencing it can’t help but react to it. The goal of this project is to realize the potential of smell as art and to explore different ways of using it to interact with people."
