Although Windows 8 is out for almost a month already, the new Metro interface is heavily discussed around the web. Now images of the early stage of the design process have been posted on the web. The website IstartedSomething has posted screenshots of an Microsoft presentation by Jensen Harris, the director of program management for Microsoft's Windows User Experience Team on the Windows 8 Metro interface from 2010. At that time Metro was referred to as Pocahontas.
