We just received a set of screengrabs from an anonymous source giving us a glimpse at what appears to be Google's (and thus, the world's) future interface to its web applications, Gmail in particular. While we were originally tempted to ignore them, communications with the tipster would indicate genuine insider knowledge. Regardless, we can not independently confirm the authenticity of these images. Having said that, the pics demonstrate a more unified apps interface based on Google's Wave and accessible from any browser (as they are now). Specifically, we're told that "the goal is to provide a consistent experience throughout all Google Apps and blur the line between the browser and the website (e.g. drag and drop, right-click, etc.)." Something that certainly makes sense to us based on what we know about Google's tender approach to its Chrome browser and its future "lightweight" Chrome OS. If true then this "work in progress" also hints at the importance of Wave to the future of Google. Then again, it could be just one of many possible interface concepts from Google's burgeoning developer's sandbox.
