Prolific experimental technology artist vtol, already responsible for brainwave-reading instruments and musical tattoos, has created a device that “smells” pollution and uses the data to produce abstract art it prints on the spot like a Polaroid. Connected via Bluetooth to a computer, Digioxide can move around a city, relaying data back to a base where it will be processed. The artist explained how his creation works in the above video:

The information about the concentration of dust and harmful gasses, such as CO, CO2, HCHO, CH4, C3H8 and some others is algorithmically transformed into generative graphics, forming an abstract image.

The device is nose-shaped, sniffing the polluted air enthusiastically. The artworks Digioxide produces resemble striking pixel art, but these pretty displays are a dark reminder of the toxins we produce and breathe every day. (GIFs: Prosthetic Knowledge)
