"Facehook" is poster, made to tell bad effects of social network service(SNS). I added a fish hook to Facebook logo to send a message about SNS addiction. Facebook is the most representative SNS. And I chose Facebook logo to create a message : You are addicted to SNS. A social network service has been prevalent throughout the world and is becoming a trend. As a result, people focus on SNS too much and check it excessively. It is inducing a trouble of relationship with others like friends. I hope people see this poster, thereby recognize the problem and think about damage caused by excessive use of SNS. This poster will be useful to decrease thoughtless access in SNS.
