Car pollution indicator. 
Can pollution be visible? 
How can we be a part of stopping air pollution? 
For this project i designed an origami textile flower that connects to the car exhaust and collects the small pollution particles. The purpose was to make the pollutant gases visible for us, and take an action.   
I was inspired by origami folding techniques and fabric air filters.
The fabric folds capture the pollution particles in an effective way. 
I used 3D printing technology to make an outline construction on the textile,

this helped me easily create the folded shape i wanted.
