Alberto, the author of AWN Lucido style rewrote the 3D style that comes with the default Avant Window Navigator. This change is available in the AWN Lucido PPA, but has nothing to do with the Lucid style - only the 3D style was rewritten.
You can install AWN with all these changes via the AWN main PPA - you can find exact installation instructions HERE.
Here is a video with the new 3D style in AWN Lucido:
Alberto wants feedback on this new AWN 3D style: do you like it? Hate it? Have any suggestions? Let us know in the comments!
