The original intention of this design comes from my exploration of the development law of social Internet products. Net red is essentially a kind of Internet products. Therefore, I chose this object as my creative carrier and designed an interactive system. This system is constructed based on the current popular phenomenon, and the popular taste is displayed through four types of net red. The viewer scans the QR code to enter the mobile phone to experience the current aesthetic orientation of the public, and creates a network red identity, which is synchronized to the live large screen for display. I want to use a positive attitude to observe the current social epidemic through humorous vision, interaction and communication.
