Of course, with the Universal release of Google Earth, Google has also kicked out a Mac OS X version of their recently-purchased SketchUp, a 3D modeling app for the masses. If you need a quick explanation, here's one as good as any from their site: "Adding a deck? Remodeling your kitchen? From simple to detailed, conceptual to realistic, Google SketchUp (free) lets you populate the world with true 3D objects."
This latest release also now supports textures, so "creating textured models is as easy as taking a photo and applying it to a 3D model". Sounds like a good time. Perhaps even better than SketchUp coming to Mac OS X is the fact that a powerful version is offered for free, while the pro version costs $495.
