Have you ever heard of sheep herding? If you haven't I'll tell you what it is and the coolest things you can do with it. Sheep herding is where a shepherd uses dogs to move sheep from pasture to pasture. In early times, sheep were used for milk and cheese.
There is a video in which the sheepherders put LED lights (like holiday lights) on the animals so that they glow and can make designs that can be seen from the air.
