a changing desktop

I want the desktop to change, dramatically. (I might as well be involved in creating that change, by the way, since I'm thinking about it.)
It's not, by the way, that I don't like the desktop as it is, and pushing for change is going to be met with resistance, for one specific reason: loosing the desktop as it is is a bad thing. Thus, the way to achieve radical change is to retain the desktop as it is, as the changes are implemented.
Note that one characteristic of the desktop today is that it hasn't changed much - only at the margins - for a long time. The science of trends suggests, based on that, that change is imminent, or, more properly, that there is a ready potential for it.
