I tried the Jung-uk patch, and figured out how to get the cube rotating 
on compiz (must load "cube", then "rotate" plugins). It works really 
well, after I've told the workspace-switcher that there's only one 
workspace (and a number of other tweaks). All of the cube features work 
marvelously (including moving it around while watching a youtube video, 
without skipping). The water plugin works very well too.

I experience intolerable slowness when trying to use the normal "0" mode 
for resize (where the window is updated as it is resized, in real-time). 
I have gone to mode "2" (rectangle) mode, which draws a shaded rectangle 
as the window is redrawn. I have historically had poor performance w/ 
the real-time window updates during resize, anyhow.

Anyhow, thank a lot for the help. Now I have a nice bunch of eye-candy 
in my window manager (and get to make better use of my 3D card).
