Came across this interesting development whilst browsing Mashable.com today.  

Introducing In-Page Analytics: Visual context for your Analytics data

Basically, Google provide a site overlay view in their Google Analytics package.  And it's not brilliant; even they admit it.  So they've decided to take things a step further, and to implement a far more visual approach that superimposes the analytics data on the page, right there in front of you.  We gave it a try (the option can be found in the Content sub-menu) but it wouldn't work in FireFox or Google Chrome.  The software is very clearly labelled Beta though; so you might have more luck.  If not, satiate yourself with the videos on the official page.

Looks like it could be very useful in the future!
