Prototyping: Creating a cell phone flashlight in Unity

Every so often a student will come to me asking how to create a specific asset for their game, and in helping them work through the process of creation, I realize that it would be a good subject for a class tutorial. The guides that come from these situations are usually very quickly thrown together and utilize polygon primitives. The code might not be the cleanest, but it's a good starting point for a concept asset.
