I have recently seen a very interesting blog post from Edward Wilde who has been able to integrate a SharePoint KPI list with a digital picture frame. This allows a CxO/Manager to track organisational performance very easily. I think this is a great idea and one which may catch on if developed further.
The picture frame works by rendering the RSS feed from the KPI List. I look forward to further developments in this realm, as Ed outlines in his post. See http://blogs.edwardwilde.com/ for more info and the source code.
