Hi everyone!! I've just made another panel proposal based on metal textures (silver, gold and copper). You can see the work here: <a href="https://wiki.ubuntu.com/Artwork/Incoming/AlvaroPanel">https://wiki.ubuntu.com/Artwork/Incoming/AlvaroPanel
</a>. This proposals are based on <a href="https://wiki.ubuntu.com/Artwork/Incoming/EffraiePanel">EffrairePanel</a>. Feel free to critizice and modify and do whatever you want! Sorry but now I can't try the panels because I'm not at home so I don't have my computers with ubuntu. If you want to try it on your ubuntu please make a screenshot and upload it.
