This is all of Compiz, with helper apps like Compiz Fusion Icon, and Emerald Theme Manager, combined with my Switcher app that uses Compiz to animate the desktop. 102 mb.
Tested on BookwormPup64, but typing 'compiz --replace & 'in JWM will exit you to a command prompt. Starting X with 'xwin compiz', and then doing 'emerald --replace &' does work. Or you can use this xfce4-minimal.sfs (6.7 mb) and log in with 'xwin xfce4-session', and then use 'Compiz Fusion Icon' to start it.
This Debian package will download Compiz and dependencies (not XFCE) automatically:
