I found this site that re-enables alot of old compiz addons that were removed with latest compiz in Mint 14
Im busy setting it up as i type this, so will report what i find working and what not. but from the comments on that page it seems alot are working so i think its a nice find for anyone that wants to re-enable old plugins for compiz
Seems it only adds a few extra plugins with version 9.
I can verify so far that the following plugins work ( ill update list as i test them ) :
Anaglyph - works perfectly.
Freely Transformable Windows - works perfectly
Throw Windows - works perfectly
