Lung Mat

I have always been a fan of mats. Not because they were my first love, or the reason I studied chemical engineering or the fact that my mum always resort using most of my favorite blankets as toilet mats but because I make my living from selling mats. Anyway, just saw this idea while surfing through wave sites looking for some killer mat picture to insert into my killer presentation.... that could potentially kill. What the hell am I saying???????
Anyway you guys think I can sell this idea to shopping mall or office building?
Anti smoking mat

My potential competition?
