Psst! excuse me..
I was on my way to subway station to meet some friends in Stockholm and heard some one coughing. I turned around and didn’t see anyone. I proceeded further thinking that it’s just an illusion, but I hear it again. So I decided to trace the sound, it lead me to this slim board standing my a waste bin. This mini billboard was embedded with couple of speakers playing the coughing sound in a loop. the message on the board urges the passer-by to donate 50 KR to people suffering from Tuberculosis in Africa.Very simple interactive idea and it does its job.
