The influence that technology and social media have on the growth and development of recent generations is becoming notably pronounced. This project is based on the TV series Black Mirror. There are many episodes in the series about the influence and problems brought by technology. As technology is becoming more dangerous, this series of posters is designed to alert people to this issue. I chose the safety poster that people usually pay attention to as the reference. I used black and yellow to make the poster stand out. I also used clear illustrations to keep information simple.
