[Orgmode] Popup with Weekly Agenda?

[Karl Maihofer]

Hi,

Tassilo integrated the weekly agenda (as a popup) with the awesome
window manager[1]. So whenever the mouse pointer enters a special region
of the desktop, a popup shows the agenda for the current week and
disappears when the mouse is moved away (Have a look at the very nice
screenshot shown in the article).

I was wondering if anybody could imagine a way to do something similar
using other window managers for X, especially Gnome.
