I personally don't consider circles/spheres to be extremely novel, they're just in there to highlight the design process and the fact that there seems to some unexplainable similarities in naming.

I do consider the interactive planner to be novel, as with currents which share the name as google currents.

More so than this, we have developed a system for identity management called Personas which we demo'd in Beijing a couple of months ago. All signs point to google releasing this system in the very near future despite claiming they wouldn't. I predict it will have the same name also.
