we placed a mirror with webcame against the wall and placed the projector opposite the mirror.Then we placed this items at a public place where people who walk frequently.People who passed by this area will be shocked or reacting to the sound which will be projected from the speaker and he/she could see the image of their own self in the projector's screen.

a bulb is placed to indicate when people's emotions are being projected to the wall.
