The KDE Native Widget Framework for OpenOffice.org gives OOo the 'look'
(but not the 'feel') of your Qt theme.
The KDE VCLplug project is replacing OpenOffice.org's drawing routines and
event handling with Qt events. ('Look' and 'feel' are still the same, but the
underlying code is different.)
"cuckooo" is a KDE Part, which allows OpenOffice.org to be run in a Konqueror
window.
