Compiz settings manager/Effects/3D windows. But you must install other CF packages
compiz-fusion-plugins-extra-0.8.4-1pclos2010
compiz-fusion-plugins-unsupported-0.8.4-1pclos2010
compiz-fusion-plugins-main-0.8.4-1pclos2010
....
I loaded the plugins, but I don't know which configuration settings to enable. I checked 3D Cube Model, but it doesn't produce the effect.
EDIT: I'm in idjit. I loaded the wrong plugins. Fixed it now.
Solved.
Thanks, coffeetime
