My colleagues and I are searching for examples of Perl as a successful desktop development language. While the presence of several good GUI toolkits (Tk, Gtk, Win32, QT, and wx) is indisputable, it's hard to overcome conceptual barriers without being able to point to a widely deployed or otherwise successful project.

I've only personally been able to come up with the Mandrake GNU/Linux administrative utilities and pVoice.

Are you developing, using, or aware of any desktop applications written in Perl?
