To bring the ink to life, Graviky Labs founder Anirudh Sharma and his team created a series of tools that attach to pollution emitters like the tailpipes of cars. Once in place, the device captures any raw carbon and soot that might seep into the air. That is then put through a purification process to ensure its safe for anyone to use.
Tiger then took the product to up-and-coming street artists in Asia, a region facing major pollution concerns, and asked them to work their magic with the spray paint and pens.
