Processing is a programming language in the context of visual art. Processing is developed for electronic art and visual design fields to teach non-programmers the basics of computer programming in a visual context. This application was created in a two-week course. The module was very experimental and self-paced. Through various inputs and self-research, the application "Rollercoaster of Emojis" was created. With it, a picture or poster can be created from the common emojis in a playful way according to the current emotional state. ©ZHdK 2019
