No, not an external project, just one of the "official" rxvt variants. I use the same one on linux as on cygwin/X.
rxvt-unicode-256color
I use it on cygwin at work because I use it on linux at home, because of the tabs (which are text-based and have nothing to do with whatever desktop environment it's running in), and because the 256 colors make it easier for me to distinguish different code parts in a colored text editing session.
The default terminal in cygwin is OK, but the small number of colors were really bothering me (old eyes).
As for unicode, I've displayed Japanese and other scripts in rxvt-unicode-256color just fine.
