With the assistance of 3D scanner, I re-produced a 3D model of a gas mask from cardboard-made model I wear to join on the street demonstrate, the symbol of HK democratic movement. The physical object then could be mass replicated and disseminated on the virtual public space.

The face recognition function could be ironically activated on political figures, such as a gas mask wearing on Carrie Lam, the Chief Executive of Hong Kong, to sing the (unofficial) Hong Kong anthem created by/for the movement supporters.

When 2D image recognition is implemented in a 3D environment, there's a possibility of advocating on social/political issues by targeting objects then revealing animated images with another context.
