As far as I can tell, there are no additional “themes” out there. But I did find the SVG files the clock uses in
/usr/share/gnome-do/ClockTheme
It would be easy enough to replace these; ideally I guess there would be a section in the GNOME Do wiki to upload clock theme packages. The hands of the clock are another matter, generated by Do itself. As it is, I’ve never created an SVG in my life, so I’m stuck with a numberless clock for now.

Howdy, I am the author of Docky. Just wanted to let you know that the themes used are actually cairo-clock themes, so they all work. In the future the hands will be drawn from svg’s also, just never really got around to it.

Oh hey DBO; first, thanks for giving us Docky! I love it and can’t wait to see how it improves. And also, yeah, I did notice some time ago that the themes were cairo-clock themes, I just never bothered to update this post. Thanks for the note.
