Following our Plants Not Pollution project, Hammersmith & Fulham Borough Council and the Hammersmith BID invited us to design supergraphics for another section of the Hammersmith Flyover. We asked ‘how might we combat the awful affect air pollution has on our health?’. In our research we were shocked to discover how air pollution degenerates our cognitive ability. Brainteasers is a project to counter the effects of air pollution — by keeping local minds stimulated. Each maze and riddle was designed and tested so that it couldn’t be solved in the time it takes to pass by — our aim was to keep local minds engaged as they travel under the Flyover every day.
