Processing is fun! In this project, I've made 2 different sketches again. The first one is one light hanging on the ceiling and waving around and showing the current time in the middle. It is fun to see the lantern hanging around but I want a better output. The second one is the one using Perlin Noice to create a vector grid then the blue arrows will flow along the grid to mimic the natural water flow. The outcome is pretty decent. The grid will be regenerated every time by clicking the caravan, and the water flow is very enjoyable to look.
