This tongue-in-cheek(y) ashtray, which displays two bright pink lungs, with bronchia and all. When the smoker rest his ciggie on the side of the lung, the battery operated conscience either produces a hacking cough, or a blood curdling scream.
Implications - This is the latest in a long line of tactics used by concerned groups and government organizations aimed at encouraging smokers to quit their deadly habit. I'm not sure it'll work on hardened smokers, but I think it may have an effect on casual ones. This creative ashtray is memorable and powerful.
