A huge amount of commercial advertising is bad for you, sucking the life out of your brain and your wallet by inducing unnecessary consumerism. However, that cannot be said for a wonderfully innovative design being tried in Brazil where the mosquito-borne Zika virus is flourishing.
A company has developed a billboard that mimics the smell of humans and attracts mosquitos from more than a mile away. They are trapped in the billboard and are killed. Not only is this a remarkable use of design and engineering, it has been released under Creative Commons, allowing any city to use it.
Bravo to everyone involved, and thanks to Creative Review for passing on this information.
