Next time you're hacking up a lung from the cigarette smoke exhaled by the person next to you, maybe you can add to the stop smoking hint by wearing one of these shirts.

Warning Signs is a new brand with shirts that detect pollution in the air. FOR REAL! The shirts feature a simple drawing of either a heart or a set of lungs and veins appear on the organ when exposed to pollution. The shirt is technically sensing carbon monoxide, but the compound is present in tons of pollution including cigarette smoke, car exhaust, and other nasty environmental happiness buzzkills.

The two NYU grad students behind the concept were simply shooting for a way to emphasize what pollution does to you body on the inside, the damage you cannot see. This would be a way of seeing it as it's happening. Sort of like those nasty "What if hepatitis did to you on the outside what it does on the inside?" posters from high school health classes. Except this is a little bit more fun and flashy as opposed to plain old horrifying.

When can I get me one?! Well hopefully soon as the pair is hoping to put these out on the market as soon as they can.

In the meantime they are working on an alcohol sensor that would work in a similar way. So instead of discovering you've had a little too much as you fumble to the bathroom or as you blow into the breathalyzer you could be keyed in to your BAC by the liver on your shirt as it subtly lights up. Wowza!
