I think this infographic is cool, I really do. It’s all about these bizarre and different looking roofs. Some of them have descriptions and reference points and some don’t. I recommend 
you looking at each and deciding whether or not you might consider one of these for your own home or place of business. I would definitely go with “Roof of the Core” it definitely would scare away the birds and other animals. Infographic-Roofs-Around-the-World
