2017 – The All Too Evident Ashtray

The ATEA is an ashtray made of concrete. It carries data about smoking habits & lung cancer in the United States between 1975 and 2014, split by gender. The data is encoded in concentric bubbles/half spheres, where the distance to the center shows lung cancer prevalence by year. The bubble diameters display the average number of cigarettes smoked per day during that particular year.

The causal relationship between smoking and cancer is well researched and known for decades, so there’s really no new information or new insight in there.  But just in case they forget for a second, the All Too Evident Ashtray reminds it’s user of that fact.
