So if I get it right you mean some kind of "effect plugins" which can be 
individually applied to a widget depending on what features (OpenGL, 
COMPOSITE) are available? Sounds good :)

It would be cool if the user could create the "chains" himself in a simply 
way. Maybe a controlcenter module for configuring the effects. For example he 
wants the widget to fade in and then to do some rotation. And then he simple 
opens the control module, chooses the effects, puts them in some particular 
order and his new eye candy is ready to go :)
