Comment 4 for bug 71071

packages have changed under feisty, no more libindustrialtango.so

you'd need to do the follow to achieve what I outlined for edgy
(see attached image for end result)

1) apt-get install gtk-engines-industrial industrialtango-theme

2) create /etc/gtk/gtkrc and insert the following
=============================================================
include "/usr/share/themes/IndustrialTango/gtk/gtkrc"

style "default-text" {
fontset = "-adobe-helvetica-medium-o-normal--10-100-75-75-p-57-iso10646-1,\
           -*-r-*-iso10646-1,*"
}

class "*" style "default-text"
=============================================================

also: it wouldn't be too hard to modify industrial-tango to make industrial-ubuntu...
