Textile chemist Lauren Bowker develops inks that respond to various changes in the climate, giving invisible shifts in the wearer's environment a visible manifestation and giving the wearer a new look from microclimate to microclimate.

While studying at the Manchester School of Art, Bowker developed PdCl2, a Carbon emission sensing ink, before going on to study printed textiles at the Royal College of Art London. Her PHNX fashion pieces are elaborate feathered costumes dyed with an ink that responds to air pollution, UV, heat, moisture, and air friction, so that the feathers change color with both the climate and the wearer's movements. In an interview with Dezeen, Bowker suggests that she could design an outfit that reacts to very minute changes in geography:

If you came to me and said 'Lauren, I want my silk jersey to change colour when I'm at Oxford Street, then when I'm at Baker Street I want to be a different colour', I would go out and map the fluctuations in the environment of each tube station then I would create you an ink that responds to those environments.

And the inks don't need to be added to feathers; they can be painted, screenprinted, dyed, or sprayed on various materials.
