I spent a good long time looking for a steampunk themed skin for my dock and found, nothing, not a single one, plenty of icons, widgets etc but no skins sooo i made my own, i think it came out pretty good so decided to share it, please let me know if you like it :)
Installation is easy, navigate to C:/Program Files (x86)/RocketDock/Skins and just put the folder called Steampunk in there :)
on some systems it may just be "program files" without the (x86)
