1. To use emerald you must have compiz running.( plus accelerated graphic card and 3rd party drivers.)
connect to net and type in terminal:
sudo aptitude search emerald, (to search for emerald)
sudo aptitude install emerald,
2.WINE can be installed similarly.
3. desktop can be animated using x-video overlay.( in fact you can put any video file as our desktop background.)
