This is based on the leaves from “Droplets”. Essentially, the leaves are turned on their sides, and become blades of grass, pushed (or, if you’re poetic, ‘caressed’) by the wind. Each blade is made up of up to 17 particles: a root particle, which anchors the entire blade, and then a series of particle pairs describing its position. Each pair has a fixed particle which is the ‘preferred’ point for that node, and a flexible particle, which can move freely. These pairs are connected with springs, and each flexible particle is also connected to the flexible particle before it with a spring. This keeps everything together but moving fairly organically.
