This actually happened some time ago but the Mac version finally released today so I’m mentioning it now. Google bought the company some months ago and announced a free version which is somewhat feature limited compared to the commercial (~$495) version but still very capable and useful for things from shelf construction in the garage to landscape planning for the yard. If you’re not familiar with it, Sketchup is a wonderfully intuitive Computer Assisted Design (CAD) program for macs and pcs. The Mac version is not yet a universal binary but it runs and performs competently enough. It’s also integrated with google earth so you can add the fabulous garden of eden you design for your backyard to the global info-stream should you so choose.
I originally notice this over on the unofficial apple weblog, but you can also link directly to the download on google’s site.
