I plan to develop a network of physical widgets all over the city to inform pedestrians about current Air Quality Index in their neighborhood. This is needed to improve people conscious about their environment pollution to start them acting against.
- one of 6 colors
- and up to 3 digits number
It should be possibly cheap and easily recognized form moving vehicles (target: public transport) and from some distance.
I plan to put those widgets in friendly venues (shops, offices, even flats).
Just for reference, here http://www.livinglightseoul.net/ is an example of such installation.
