A wall that would deter a smoker from smoking in a friendly and a non annoying way.
I am imagining that it would react to smoke and respond in a friendly and not a preachy way to kick the butt. I am not really clear how it would, but I want to do the research to make it convey the exact thing. I really don't want to scare people into not smoking the way cancerous lungs look. I honestly think that it is more putting off than getting home the point. I want to ponder over this a little bit longer and bounce ideas off in class to gain some clarity on its potential.
