Hmm.. Google is one company which is known for innovation and uniqueness in their software.. The latest offering from the Google stable is Google SketchUp! Google SketchUp is an easy-to-learn 3D modeling program that enables you to explore the world in 3D. With just a few simple tools, you can create 3D models of houses, sheds, decks, home additions, woodworking projects – even space ships. And once you’ve built your models, you can place them in Google Earth, post them to the 3D Warehouse, or print hard copies. Google SketchUp is free for personal use. No registration is required.
