A lot of skins were included in Live 2, so I've recreated five more of them that you can download for free as well. The ones I remade as Live 10 themes are Graphite, Pilz, Smog, Swamp and Tucson.
Get more free themes. You can still download the Live 9 skins. If you don't know how to install them, have a look at this tutorial, and if you'd like to create your own themes, I've got a tutorial for that as well.
