Water is the source of life. Nowadays, water resources are very shortage, we should concern this problem. Water scarcity causes water rationing in Taiwan in 2021. Our inspiration came from the ocean. In visual effect, using creative coding to present the ocean’s different forms and colors, and we designed posters for print. We used particle effect and Perlin noise, which can undulate with sound and interact with mouse. Logo design is a traditional Chinese character “?“, which means in English “water”. We hope that through this project let everyone knows that water is essential to life.
