houthakker in the Mac OS X Tips Geeklets section:
It can be useful to glance at a key OmniFocus action list on the desktop, without having to fire up OmniFocus and choose a perspective. (A red Due Now list perhaps, or an orange Due Soon, or a context list, or simply the Inbox, as a spur to getting it clear). Here is an applescript which enables you to attach a range of customized list specifiers to one or more Geektool ‘windows’ (shell geeklets) at the same time.
Basically you can print a bunch of OmniFocus data to your desktop. The value? I don’t know, but is sure looks cool. ((Haven’t tested it yet, intend to this weekend.))
